An inventory of winds trapped with a curious device: the artist from Bordeaux places piles of cardboard boxes, plastic bags and other light elements in the ditch of a series of French roads. The filmed traffic causes the gust as it passes by and makes the improvised towers shake or fall, depending on the force of the wind that the vehicles create as they go past.  Between conceptual and burlesque, in this first attempt to trap the wind, the air enters the scene with all of its invisibility.
