Is Michel Comte’s past celebrity a burden? “You carry it on your fucking back,” he says. “It took ten years for people to notice I was visiting Africa for months at a time. It took twenty years before people starting listening to what I’ve been saying since my first gallery show.”
A COUPLE of days before the opening of Trevor Paglen’s latest photographic installation, From “Apple” to “Anomaly”, a related project by the artist found itself splashed all over the papers.
ImageNet Roulette is an online collaboration with artificial intelligence researcher Kate Crawford at New York University. The website invites you to provide an image of your face. An algorithm will then compare your face against a database called ImageNet and assign you to one or two of its 21,000 categories.
ImageNet has become one of the most influential visual data sets in the fields of deep learning and AI. Its creators at Stanford, Princeton and other US universities harvested more than 14 million photographs from photo upload sites and other internet sources, then had them manually categorised by some 25,000 workers on Amazon’s crowdsourcing labour site Mechanical Turk. ImageNet is widely used as a training data set for image-based AI systems and is the secret sauce within many key applications, from phone filters to medical imaging, biometrics and autonomous cars.
According to ImageNet Roulette, I look like a “political scientist” and a “historian”. Both descriptions are sort-of-accurate and highly flattering. I was impressed. Mind you, I’m a white man. We are all over the internet, and the neural net had plenty of “my sort” to go on.
Spare a thought for Guardian journalist Julia Carrie Wong, however. According to ImageNet Roulette she was a “gook” and a “slant-eye”. In its attempt to identify Wong’s “sort”, ImageNet Roulette had innocently turned up some racist labels.
From “Apple” to “Anomaly” also takes ImageNet to task. Paglen took a selection of 35,000 photos from ImageNet’s archive, printed them out and stuck them to the wall of the Curve gallery at the Barbican in London in a 50-metre-long collage.
The entry point is images labelled “apple” – a category that, unsurprisingly, yields mostly pictures of apples – but the piece then works through increasingly abstract and controversial categories such as “sister” and “racist”. (Among the “racists” are Roger Moore and Barack Obama; my guess is that being over-represented in a data set carries its own set of risks.) Paglen explains: “We can all look at an apple and call it by its name. An apple is an apple. But what about a noun like ‘sister’, which is a relational concept? What might seem like a simple idea – categorising objects or naming pictures – quickly becomes a process of judgement.”
The final category in the show is “anomaly”. There is, of course, no such thing as an anomaly in nature. Anomalies are simply things that don’t conform to the classification systems we set up.
Halfway along the vast, gallery-spanning collage of photographs, the slew of predominantly natural and environmental images peters out, replaced by human faces. Discrete labels here and there indicate which of ImageNet’s categories are being illustrated. At one point of transition, the group labelled “bottom feeder” consists entirely of headshots of media figures – there isn’t one aquatic creature in evidence.
Scanning From “Apple” to “Anomaly” gives gallery-goers many such unexpected, disconcerting insights into the way language parcels up the world. Sometimes, these threaten to undermine the piece itself. Passing seamlessly from “android” to “minibar”, one might suppose that we are passing from category to category according to the logic of a visual algorithm. After all, a metal man and a minibar are not so dissimilar. At other times – crossing from “coffee” to “poultry”, for example – the division between categories is sharp, leaving me unsure how we moved from one to another, and whose decision it was. Was some algorithm making an obscure connection between hens and beans?
Well, no: the categories were chosen and arranged by Paglen. Only the choice of images within each category was made by a trained neural network.
This set me wondering whether the ImageNet data set wasn’t simply being used as a foil for Paglen’s sense of mischief. Why else would a cheerleader dominate the “saboteur” category? And do all “divorce lawyers” really wear red ties?
This is a problem for art built around artificial intelligence: it can be hard to tell where the algorithm ends and the artist begins. Mind you, you could say the same about the entire AI field. “A lot of the ideology around AI, and what people imagine it can do, has to do with that simple word ‘intelligence’,” says Paglen, a US artist now based in Berlin, whose interest in computer vision and surveillance culture sprung from his academic career as a geographer. “Intelligence is the wrong metaphor for what we’ve built, but it’s one we’ve inherited from the 1960s.”
Paglen fears the way the word intelligence implies some kind of superhuman agency and infallibility to what are in essence giant statistical engines. “This is terribly dangerous,” he says, “and also very convenient for people trying to raise money to build all sorts of shoddy, ill-advised applications with it.”
Asked what concerns him more, intelligent machines or the people who use them, Paglen answers: “I worry about the people who make money from them. Artificial intelligence is not about making computers smart. It’s about extracting value from data, from images, from patterns of life. The point is not seeing. The point is to make money or to amplify power.”
It is a point by no means lost on a creator of ImageNet itself, Fei-Fei Li at Stanford University in California, who, when I spoke to Paglen, was in London to celebrate ImageNet’s 10th birthday at the Photographers’ Gallery. Far from being the face of predatory surveillance capitalism, Li leads efforts to correct the malevolent biases lurking in her creation. Wong, incidentally, won’t get that racist slur again, following ImageNet’s announcement that it was removing more than half of the 1.2 million pictures of people in its collection.
Paglen is sympathetic to the challenge Li faces. “We’re not normally aware of the very narrow parameters that are built into computer vision and artificial intelligence systems,” he says. His job as artist-cum-investigative reporter is, he says, to help reveal the failures and biases and forms of politics built into such systems.
Some might feel that such work feeds an easy and unexamined public paranoia. Peter Skomoroch, former principal data scientist at LinkedIn, thinks so. He calls ImageNet Roulette junk science, and wrote on Twitter: “Intentionally building a broken demo that gives bad results for shock value reminds me of Edison’s war of the currents.”
Paglen believes, on the contrary, that we have a long way to go before we are paranoid enough about the world we are creating.
Fifty years ago it was very difficult for marketing companies to get information about what kind of television shows you watched, what kinds of drinking habits you might have or how you drove your car. Now giant companies are trying to extract value from that information. “I think,” says Paglen, “that we’re going through something akin to England and Wales’s Inclosure Acts, when what had been de facto public spaces were fenced off by the state and by capital.”
Untitled Gallery was founded in Sheffield in 1979. It specialised in photography. In 1996 it was renamed Site Gallery and steadily expanded its remit to cover the intersection between science and art. Nearly 30 years and a £1.7million refit later, Site Gallery is the new poster child of Sheffield’s Cultural Industries Quarter, with an exhibition, Liquid Crystal Display, that cleverly salutes its photographic past.
Most shows about art value the results over the ingredients. The picture matters more than the paint. The statue matters more than the stone. Exhibitions about photography give rather more space to process because photography’s ingredients are so involved and fascinating.
Liquid Crystal Display follows this photographic logic to its end. This is a show about the beauty, weight and messiness of materials we notice only when they’ve stopped working. It’s about the beauty created by a broken smartphone screen, a corroded battery, a cracked lens.
Site Gallery’s new exhibition – a cabinet of curiosities if ever there was one – collides science and art, the natural and the manufactured, the old and the new. It puts the exquisite sketches of 19th-century Scottish chemist and photographer Mungo Ponton (detailing his observations of how crystals polarise light), next to their nearest contemporary equivalent: microscopic studies (pictured) of liquid crystals caught in the process of self-organisation by Waad AlBawardi, a Saudi molecular biologist who’s currently in Edinburgh, researching the structure of DNA organisation inside cells.
This provocative pairing of the relatively simple and the manifestly complex is repeated several times. Near a selection of crystals from John Ruskin’s mineral collection sit the buckets, burners and batteries of Jonathan Kemp, Martin Howse and Ryan Jordan’s The Crystal World project, a tabletop installation recording their hot, smelly, borderline-hazardous effort to extract the original minerals from bits of scavenged computers. Curated by Laura Sillars, assisted by Site Gallery’s own Angelica Sule, Liquid Crystal Display reveals the material, mineral reality behind our oh-so-weightless holographic world of digital imagery. “Liquid crystals polarise light, produce colour and yet, as a material form, recede into the background of technology,” Sillars wrote in the catalogue to this show.
This awareness is not new, of course. In the 1960s, liquid crystals were being burned on overhead projectors to create psychedelic light shows. J G Ballard’s novel The Crystal World (1966) concocted a paranoid vision of a world and a civilisation returned (literally) to its mineral roots. That story receives a handsome homage here from the scifi-obsessed Norwegian artist Anne Lislegaard, whose stark monochrome animation (above) turns the sharp shadows and silhouettes cast by contemporary domestic furniture into insidious crystalline growths.
Arrayed within Anna Barham’s peculiar hexagonal cabinetwork, a gigantic piece of display furniture that is itself an artwork, the pictures, objects, films and devices in Liquid Crystal Display speak to pressing topical worries – resource depletion, environmental degradation, the creeping uncanny of digital experience – while at the same time evoking a peculiar nostalgia for our photochemical past.
The exhibition lacks one large signature object against which visitors can take selfies. A peculiar omission in a show that’s relaunching a gallery. And a bit of a shame for an exhibition that, in its left-field way, has handsomely captured the philosophical essence of photography.
Microphotography has come along way since Nikon staged the first Nikon Small World competition in 1974. Finalists in 2018 harnessed a dizzying array of photographic techniques to achieve the spectacular results displayed here. A full-colour calendar of the winners is in the works, and people in the US can look forward to a national tour of the top images.
Yousef Al Habshi from the United Arab Emirates won first prize with the image above of the compound eyes and surrounding greenish scales of a weevil, Metapocyrtus subquadrulifer. It was made by stacking together 129 micrographs — photographs taken through a microscope. “I feel like I’m photographing a collection of jewelry,” said Al Habshi of his work with these beautiful Philippine beetles, which are more usually considered agricultural nuisances and targets for pest control.
Rogelio Moreno from Panama won second prize for capturing the spore-containing structures of a fern (above). He used a technique called autoflorescence, in which ultraviolet light is used to pick out individual structures. Spores develop within a sporangium, and Moreno has successfully distinguished a group of these containers from the clustered structure called the sorus. Sporangiums at different stages of development show up in different colours.
Saulius Gugis from the USA photographed this spittle-bug in the process of making its “bubble-house”. The foamy structure helps the insect hide from predators, insulate itself and stay moist. The photograph won third prize.
Other highlights from the prize include a portrayal of the first stirrings of arachnid life by Tessa Montague at Harvard University. The surface of this spider embryo (Parasteatoda tepidariorum) is picked out in pink. The cell nuclei are blue and other cell structures are green.
Looking for all the world like an extra from Luc Besson’s sci-fi film The Fifth Element, this magnificent mango seed weevil (Sternochetus mangiferae) earned Pia Scanlon, a researcher for the Government of Western Australia, a place among the finalists.
THE lasting geological impact of our species is clearly visible within the galleries of this potash mine in Russia’s Ural mountains. The Urals contain one of the largest deposits in the world of this salt, one of the most widely used fertilisers. Mining has left behind vast subterranean galleries, their walls machine-carved with enormous ammonite-like whorls.
The Canadian photographer and artist Edward Burtynsky took this photograph for The Anthropocene Project, a collaborative chronicle of geologically significant human activity such as extraction, urbanisation and deforestation. Works from the project are on display at the Art Gallery of Ontario and the National Gallery of Canada, while this image and other photographs feature in Burtynsky’s exhibition The Human Signature, at London’s Flowers Gallery, to 24 November.
This September also saw the release of a documentary film, Anthropocene: The human epoch, and a book of colour photographs by Burtynsky, which includes new writing from author and poet Margaret Atwood.
Through publications, films and immersive media, Burtynksy and his Anthropocene Project collaborators – filmmakers Jennifer Baichwal and Nicholas de Pencier – convey the unsettling visual reality of resource depletion and extinction: how our planet’s surface is being scarred, ground and shovelled into abstract, almost painterly forms.
The effects of mining, in particular, are irreversible. While animal burrows reach a few metres at most, humans carve out networks that can descend several kilometres, below the reach of erosion. They are likely to survive, at least in trace form, for millions or even billions of years.
There is an eerie poetry to this: burrows found in 500-million-year-old sediment tipped off geologists to the massive diversification of animal forms known as the Cambrian explosion. Will our own gargantuan earthworks commemorate more than just a mass extinction event?
Visit the Rhône Glacier in southern Switzerland, and you are more than likely to wander past a small shop. It’s worth a visit: the owners have carved out an ice grotto, and charge tourists for the eerie and beautiful experience of exploring the inside of their glacier’s mass of blue ice.
Now, though, it’s melting. The grotto is such an important part of their livelihood, some years ago the owners invested 100,000 euros in a special thermal blanket. “It’s kept about 25 metres’ depth of ice from disappearing and has kept the grotto in business,” explains the photographer Simon Norfolk. But a few winters on the mountain have left the blanket in tatters.
“It’s the gesture that fascinates me,” says Norfolk. “There is something insane about trying to reverse the inevitable – a gesture as forlorn and doomed as the glacier itself.”
Norfolk and fellow photographer Klaus Thymann climbed up to the grotto just before dawn, armed with a light attached to a helium balloon that cast a sepulchral light over the scene. “I wanted to recreate the same light you get over a mortuary slab,” Norfolk says.
Emilia van Lynden, artistic director of Unseen Amsterdam, finds the effect as aesthetically chilling as it is beautiful. Of the whole series, called Shroud, she observes: “We’re seeing a glacier being wrapped and prepared for death.”
“There’s next to no photo-journalism here,” van Lynden explains. “None of the images here expect you to take them at face value. They expect you to pay attention and figure things out for yourself. These are works into which you need to invest a little bit of time and effort, to see what the artist is trying to tell you.”
On the face of it, then, the presence at Unseen of Project Pressure, Norfolk and Thymann’s campaigning environmental charity, seems odd. The whole point of the outfit, which has collaborated with the likes of NASA and the World Glacier Monitoring Service, is not just to get us to think about climate change, but to do something positive about it.
But art photography, Norfolk and Thymann believe, is a more effective communication tool than straightforward photo-journalism.
Their point is eloquently made by this 24 hour time-lapse video, created with a thermal imaging camera. By revealing the heat-properties of the scene, Norfolk and Thymann underline the different temperatures in the ice-body versus the surrounding landscape – a key indicator of climate change.
“I believe artists often make the best social and environmental investigators,” says van Lynden. “The trouble with ‘straight’ photography is it looks for stunning subjects and leaves you, well, stunned by them. Glaciers are magnificent in their natural form even as they’re melting away.”
The series exhibited in Project Pressure’s show When Records Melt take a different approach.
Among van Lynden’s favourite works are photographs by Christopher Parsons, who is better known for photographic portraits of explorers and sports personalities. Parsons won Project Pressure’s open call, and was invited on an expedition to the Himalayas. He collaborated with scientists studying alterations in the microbial life around retreating glaciers, and his photographs, while full of dread, are also accurate records of how changing weather patterns are altering the course of life in these fragile environments.
Adam Broomberg and Oliver Chanarin also take an apparently left-field approach to glacier retreat that nonetheless packs a powerful emotional punch. “Their work is literally a huge photograph of a bone that was found within the Rhône glacier,” says van Lynden. “They’re looking at the glacier as a living archive that now is slowly unravelling. All this information, all this stored data, which has been locked in the ice for however many thousands of years, is being lost.”
She is in no doubt that Project Pressure’s message is clear. If you’re not convinced by one series of photographs, says van Lynden, “then you have six other projects that showcase, each in its individual manner, the irreparable damage we have done to our planet.”
IT’S not often that artists presenting new work ask for the lights to be turned off, but here it makes sense. We hunker in the dark of hall 2 at the Messe Basel exhibition centre in Switzerland as tiny lights spill over the mesh sides of a large mechanical sculpture, producing tracks and spirals, and interference.
There is plenty of noise, too: HALO is essentially a gigantic bass harp, playing a score derived from raw data from the Large Hadron Collider (LHC) at CERN near Geneva. In 2015, CERN’s art programme hosted Joe Gerhardt and Ruth Jarman, who make art under the name Semiconductor; HALO is the most recent work to come out of that residency.
Its construction was commissioned by Swiss watch-maker Audemars Piguet, which has championed some of the biggest names in scientifically inflected art since 2012. In partnership with Art Basel, Europe’s biggest art fair, the company has backed the strangest projects. Take Robin Meier‘s jungle-like installations, inspired by the synchronous flashes of fireflies; or Theo Jansen‘s Strandbeests – eerily lifelike and intentional automata made of recycled plastic.
This isn’t mere “sponsorship”; it’s Renaissance-style patronage. The company’s engagement with and promotion of artists extends well beyond the launch of any individual artwork.
Once HALO has stopped reverberating, Jarman talks about how Semiconductor got started 20 years ago. “We were interested in matter, and how science provides us with the tools to perceive matter and material processes that would otherwise be hidden from us,” she says.
Acts of perception matter to artists, while scientists are more interested in the information those perceptions contain. HALO came about, Gerhardt recalls, through the artists’ desire to work with readings that were as close to natural perception as possible, before all the artefacts and noise are stripped away. “We spent three months working through the hierarchy – fighting our way to the vault, if you like,” he says.
It’s a point not lost on Olivier Audemars, HALO‘s patron. Although neither he nor his colleagues are directly involved in the commissioning process, he is as fascinated with science as with the art his company supports. The first scientists took their measures and concepts of time from the watch-makers, he explains the day after HALO‘s unveiling. “The greatest names in science used this analogy of the watch-maker to explain their vision of the universe, including Einstein of course, with his claim that God does not play dice with the universe,” Audemars says. “Though in that case,” he smiles, “it seems he was wrong.”
Technical and scientific interests drive a company like his, and shape its culture. “If I have an interest in cosmology and quantum physics, it’s because I’ve had those conversations, with my parents, even my grandparents.”
The artists who win commissions are invited to the company’s headquarters in the Swiss town of Le Brassus, and seem to fall quickly under their patron’s spell. Art history is not short of examples of this sort of arrangement going horribly wrong. But then, not every patron is a watch-maker, whose employees must couple art and science, mechanism and craft.
Jansen’s Strandbeests (on show this week in Singapore) are mechanism personified. Meier’s fields of artificial fireflies (last seen earlier this year in Thailand) are governed by how neighbouring pendulums synchronise. And HALO is a homage to the LHC – the largest machine in history – and a homage made mostly of one-off, handcrafted parts. The fact that on maps the LHC resembles a giant watch is, surely, just a coincidence.
At this year’s Art Basel, the walls of the Audemars Piguet collectors’ lounge displayed recent works by the Italian-born, London-based artist Davide Quayola. The company invited Quayola, whose work uses new technologies in unfamiliar ways, to take pictures around Le Brassus. The upshot was Remains – outsize, phenomenally high-resolution images of dense woodland, generated by laser scanning.
Quayola says that he wanted to look at the valley, not with his own eyes, but through the eyes of a machine. He goes on: “I wanted to hand over to the machine the traditional activity of walking out into the landscape in search of an encounter with nature. For me, technology is not a tool. I prefer to think of it as a collaborator, engaging with things in ways unique to itself.”
It is a collaboration of equals, although initially the machines had the upper hand. “Scanning the valley using lidar technology was much more complicated than I had expected,” Quayola admits.
First there was the sheer amount of time required, with each scan taking some 10 minutes as the “camera” turns full circle, shooting out tens of millions of laser beams. And then there are the readings it gathers, which only make sense from one vantage point. To really capture the environment can take up to 60 scans for a single patch of forest. There’s a final complication: all those scans must be correctly linked to yield a coherent map of an area constantly being buffeted by the weather.
The resulting images are clearly not photographs, but equally clearly are not the product of the human eye. Get up close to this cloud of points and you can distinguish each constituent; the image can not only be seen, but read. Parallel rays spill from a clump of foliage, an artefact of an uncorrected optical occlusion. And a dark, knotted surface turns out to be built up from strangely wobbly rows and columns of dots representing “thin” data, revealing the raw back-and-forth of the scanning process.
From an ordinary distance, what is startling about these works is the total absence of lines in an image that is so obviously detailed. The lidar eye has no interest in edges and planes, yet it is “seeing” with an acuity we immediately recognise as close to, or even better than, our own.
Quayola, of course, did much more than set his machines running. Since laser scanning results in a vast Excel spreadsheet, he used a computer to render the data as point clouds and then spent a while moving through them digitally, selecting the angles and frames he wanted to work on. It’s an odd process – “like being a traditional photographer, stranded somehow in a purely digital realm”, he says.
Audemars Piguet does not own what it commissions.”The work belongs to the artist,” says Audemars. “That way, the project can continue to grow.” HALO, for instance, is getting a more flexible tuning mechanism, while camera drones are contributing to the next version of Remains. “We can’t predict the life course of these projects, and we wouldn’t want to,” he says. “Artists give us new ways of seeing the world. If that process is out of our hands, good. Why would we want to spoil the surprise?”
One can taste the boosterism in the air at London’s Science Museum as it introduces its two-gallery exhibition, Illuminating India.
There is a cafe serving excellent Indian street food. Someone next to me used the word “Commonwealth” without irony. Would there have been such a spirit without Brexit? Probably not: this is a show about the genius of another country that very much wants to project Britain’s own global aspirations. Any historian of Anglo-British relations will give a sardonic smile at this.
When you visit (and you should), try to look around the smaller, artefacts-driven gallery first.
This room tells the stories of Indian science – stories plural because there can never be one, linear account of how such dissimilar and contesting cultures struggled and more or less succeeded in understanding and exploiting a space of such extraordinary complexity.
Naturally, since India has a past to boast of, pride of place goes to its indigenous cultures. It was the Indus valley civilisation, after all, whose peoples fashioned standardised weights around 4000 years ago: items that indicate high levels of arithmetical literacy, communication and trade.
And there are reconstructions of Ayurvedic surgical instruments described in records dating back to around 500 BC. Also on show is a 1800-year-old document containing the first example of the use of zero. Wonderfully, radiocarbon dating pushed the document’s age back by 500 years just before the exhibition opened.
It is a measure of the wisdom of the curators that such an illustrious past isn’t allowed to overshadow India’s more recent achievements. For example, Jagadish Chandra Bose’s early-20th-century crescograph, designed to observe plant growth at a magnification of 10,000 times, reminds us why he is often called the father of modern Indian science.
Another winning object is Chandrasekhara Raman’s spectrometer. Raman was the first Indian to win a Nobel prize, for physics, in 1930.
And what of that other great empire far to the north? Well, there is a map of George Everest’s career-defining Great Trigonometrical Survey of India – the teamwork of 70 years distilled on a single, meticulously drawn map. And nearby are details of a recent collaboration between Surrey Satellite Technology in the UK and the Indian Space Research Organisation on the Earth-surveying NovaSAR satellite.
Some of the deeper, darker questions about Anglo-Indian relations are posed in the second, photographic half of the exhibition.
There, the anthropometric photographs of Maurice Portman make a depressingly silly impression next to the respectful, revealing and entirely unlicentious photographs Ram Singh took of the women of his own harem: powerful political players all, who shaped the country through marriage and allied treaties.
It is hard to say why the split nature of Illuminating India works as well as it does. It has something to do with the way the rooms handle political power.
India’s science, from its ancient stepwells that gathered monsoon waters to the bureaucratic and algorithmic marvel that is today’s tiffin tin-based lunch delivery system, has been driven by the complex needs of a massive population making a living.
Similarly, its doing-more-with-less style of innovation is reflected in everything from the world’s cheapest artificial leg (the Jaipur leg, made of rubber, plastic and wood) to the world’s cheapest Mars-orbiting camera.
Visitors to Illuminating India will leave thinking that technology may, after all, be making the world a better place, and that what people do is ultimately more influential than who they are.
“The aim of my work is to create a visually attractive image that draws the viewer in, then shocks them with what is represented,” artist Mandy Barker explains. “This contradiction between beauty and fact is intended to make people question how their shoe, computer, or ink cartridge ended up in the sea.”
A short feature for New Scientist, 22 April 2017
Irish photographer Richard Mosse has come up with a novel way to inspire compassion for refugees. He presents them as drones might see them – as detailed heat maps, often shorn of expression, skin tone, and even clues to age and sex. Mosse’s subjects, captured in the Middle East, North Africa and Europe, don’t look back at us: the infrared camera renders their eyes as uniform black spaces.
Mosse has made a career out of repurposing photographic kit meant for military use. The images here show his subjects as seen, mostly at night, by a super-telephoto device designed for border and battlefield surveillance. Able to zoom in from 6 kilometres away, the camera anonymises them, making them strangely faceless even while their sweat, breath and sometimes blood circulation patterns are visible.
The results are almost closer to the nightmarish paintings of Hieronymus Bosch than the work of a documentary photographer. Making sense of them requires imagination and empathy: after all, this is how a smart weapon might see us.
Mosse came across his heat-mapping camera via a friend who worked on the BBC series Planet Earth. Legally classified as an advanced weapons system, the device is unwieldy and – with no user interface or handbook – difficult to use. But, working with cinematographer Trevor Tweeten, Mosse has managed to use it to make a 52-minute video. Incoming will wrap itself around visitors to the Curve Gallery at the Barbican arts centre in London from 15 February until 23 April.
