Recherche dans la filmographie: Sport, Capteur de mouvement

«Audiences encounter a video projection of an aerobics instructor who stands in silence until a viewer approaches. When a viewer moves in front of the projection and into the spotlight, the instructor begins exercising to music. If a viewer stops moving, the instructor also stops exercising and the music becomes silent. Each time a viewer begins moving his or her body, the instructor begins a new exercise with music. If a viewer exercises non-stop, the music and the instructor’s exercising will increase in tempo until an absurdly fast level is reached.»
