360° Presence, 2002
360° Presence is a 70 cm diameter ball made of steel, which starts moving as soon as someone is entering the gallery space and only stops when the gallery is empty.
As long as the movement sensors detect a physical presence in the exhibition room, the ball is continuously moving. The gallery visitor has no chance to stop it or to control the direction the ball takes. It knocks the gallery walls, clashes with the radiators and collides with the room's edges and thereby will, if not destroy, aggressively mark the white cube.
