In January 2000, for the reopening of the Centre Pompidou after several years of renovation was held the exhibition "Le temps, vite!" It was a reflection on the way in which artists and visual artists interpret the question of temporality and integrate it into their works. In accordance with the scenography imagined by François Confino, we proposed a discrete, hidden signage, which did not rely on any physical element: plans and indications were projected on the floor, while the labels, which had disappeared from the walls, were summarized in a small book distributed free of charge at the museum entrance. The idea was to enter a new, floating, misty universe, and to leave with a beautiful object, a trace of the strange experience.
