THROUGH THE GLASS, 4 simultaneous projections on the 4 walls of a room, 7 mn, 2006

Backward and forward motion, lost of all sense of space, vertigo, giddiness…marked by the permanent rhythm of the grinding chain of the swing. We can’t see who swings, it is like a ghost, a sensation, a breath making part of the surrounding space, it is a all. When, suddenly, by chance, a little girl appears in the middle of the video, she comes and breaks the monotonous swing, she fits into the video as an elementary part of it. She concretises the emptiness, she materialises at once the breath, she gives some humanity back to what it is behind the “Window”, behind this sensation.
