Take a seat inside this human-sized zoetrope, pull the bar back and forth and watch as fairytale imagery come to life around you. ‘Loop’ is the main installation at this year’s Luminothérapie, an interactive public art installation competition that takes place in Quebec each year. Developed by artists Olivier Girouard and Jonathan Villenueve in collaboration with Ottoblix, ‘Loop’ tells 13 different stories in each of the oversized illuminated circles placed along a street in Montreal.

The zoetrope, in case you’re not familiar, is a pre-film animation device that displays a sequence of images within a cylinder to produce an illusion of motion; users look through slits in the cylinder to watch it. ‘Loop’ takes this traditional object and updates it with interactivity and light, asking users to power the spinning cylinder themselves. A flickering strobe light illuminates the monochrome images lining the inside.

‘Loop’ took three months of design work and 800 hours of assembly to complete. One of the designers makes a living building Lego sets, while the other has been designing since he was just a child. Explaining how they came up with the concept, Olivier Girouard says Villanueve took inspiration from mechanical interventions at Berlin’s Technology Museum.

“Thinking of hamster wheels, we decided to build a vertical zoetrope. So we combined three mechanical elements: the railway push-car (like the ones made famous by Bugs Bunny cartoons), the music box and the zoetrope. We came up with the idea and sketched out the project just one week before the deadline for submitting proposals!”

“Our invention reminds me of the Chimera, the mythological three-headed beast born of the intersection of different universes,” says Villanueve. “I like this more or less unclassifiable hybrid machine. Is it a toy? A projection device? A kind of lighting? Looking at previous Luminothérapie pieces, we noticed that installations that were not only participatory but also collaborative, where participants had to act together to produce a result were – in our opinion – the more successful projects and the most appreciated by the public.”

Loop will light up the Place des Festivals in Montreal until January 29th, when it will take off on a tour of Quebec cities. Check out last year’s installation – a series of illuminated see-saws.

All it takes are a few highly focused beams of light and a spinning zoetrope to make a human figure spring to life, walking or even dancing in a barely-visible translucent circle. ‘Process and WALK’ explores the relationship between time and movement, taking a two-dimensional image of a person and applying it to a three-dimensional object. In effect, the person’s movements are stretched out to take up the entire circle, each fraction of an inch containing its own particular shifts of the arms and legs.

Artist Akinori Goto lays out the whole process in the video above, showing how he transforms a animation of a person walking into a 3D axis that can then be translated into data for a 3D printer. The result looks like no more than a warped piece of plastic mesh, with no discernible shapes embedded within it. Place it on a turntable and it still won’t look like much – until beams of light highlight just one segment of the edge.

Once that happens, the walking figure appears. Every few seconds, the illuminated figure seems to multiply, sending additional figures to other points along the zoetrope. It’s simple and complex at the same time, pairing a pre-film animation device that’s been in use for centuries with cutting-edge small-scale manufacturing technology
