This piece belongs to the already large family of machines and other mechanical, optical or electronic installations designed to capture, record and amplify barely visible phenomena, where art and science meet. Here, the colours imprisoned inside a grey sky are revealed, shimmering on a screen with the willing collaboration of an eye looking out for them. Once plugged in, the screen displays a program, credits listing all the operators and hands that contributed to this atmospheric, meteorological scenario to draw our gaze into a speculative adventure, beyond the mirror and appearances, along with a journey that strongly questions metamorphosed beings, spherical geometry and the internal organisation of colours. The journey begins with an image of a grey sky over St. Denis, filtered by the wind to reveal corners of blue, or completely grey, obstructed, a uniform grey veil. This veil, like a stage curtain, leads a double existence, that of a thing that attracts our gaze, with pictures and patterns, but also another existence induced by these Moiré effects attributed to the fabric without belonging to it, fading figures and sketches of movement inside the folds, a virtual existence. Within the aluminium grey frame, the clouds confirm their substance, both a visible nebulosity and a vaporous presence heavy with virtualities and mystery. It’s a sky at a specific point in the world, localised by longitude and latitude, a precise point taken from the airflows circulating in the hemisphere, in this giant “world game” or the constant battle between light and dark, a mirror of the artist’s studio, research and projects. As in Rilke’s poetry, the real world yields to virtuality, and the journey continues in a digital landscape on another scale, in another dimension of time and space, offering access to the cloud’s secret architecture, its differential modifications and its kaleidoscopic transformations, its secret, interior wealth: a random distribution of water droplets of varying size and volume, where rays of light reflect and refract, a floating carpet of bubbles open to light, the foaming time when it encounters space. It’s here, well coated in their bubbles, that the colours spread out in shimmering threads of reds, greens and blues waiting for the viewer’s eye to make them glimmer, to multiply the reflections of precious gems in a festival of colours inside a single drop of water that is reproduced in all others, with rapid variations; the colourful sparks bump into each other in their frenzied gravitation on the bubbles’ erratic orbits. More than sparks, it’s the brilliance of the grey sky! In the tradition of landscape painting, the clouds act as filters to reveal colours through their translucence, as the colour is never truly revealed until light meets its opposite, opacity and darkness. Fabien Léaustic uses his creative resources in digital media to assemble these sparks of colour, appearing then blurring into a grey sky, these passing phosphorescences, fugitive fragments, sparks that he accelerates and amplifies to create, in the here and now of the artwork, the brilliance of the present place and time.
