Elytre, a permanent generative work by Yannick Jacquet
Alexander III bridge, Paris

It has taken the Franco-Swiss artist and videographer Yannick Jacquet three years to create Élytre, a forty-metre-long generative work on display at the foot of the the Alexandre III bridge in Paris. The piece was commissioned as a permanent design feature for Le Flow, a floating building moored along the new pedestrian area on the banks of the Seine.

Yannick Jacquet drew inspiration from the dark mass of the barge between the sky and the river to fine-tune his response to the immediate surroundings, calling on the instability and permanence of the flowing water, the infinitely nuanced shifts of light, and the interplay of transparencies between its large plate-glass windows and the glass dome of the Grand Palais just across the water.

Drawing on the barge's organic, cocoon-like architecture, he came up with a highly sensitive, reactive work in the form of an installation that reverses the overall structural inertia of the barge's four hundred tons of steel, as if echoing Reyner Banham's principle of regenerative architecture.

The installation is linked up to a battery of sensors so that it varies according to the time of year, season, atmospheric pressure, wind speed, temperature, and so on. It is in a constant state of flux, permanently subject to imperceptible shifts.

As a generative work, it has its own dedicated, custom made software programme and required the artist to work closely with a team of specialists in engineering, craft manufacture, electronics, programming, and architecture.

As night falls, the work softly rises up into the surrounding cityscape. The impression on the viewer's retinas is deep and lasting. The colourful stimuli of elements emerging and fading seem to mirror the shimmering river and foliage and mimic the circadian rhythm of breathing.

The artist also devoted considerable research to the issue of colour. A metal mesh with its own unique structure is fastened over the cladding from the roof to the hull, creating a pointillist effect by means of an infinite palette of pixels. The material resists the quantity of light and contrast: the artist has sought to create nuances and shadings of colour by pushing LEDs beyond their usual capacities.

Yannick Jacquet explains that the installation is part of a broader project exploring cycles and our relationship with time. The work is designed less as an invitation to a journey as an order to slow down. To take the time for contemplation.
