A diagonal wall covered with black velvet divides a square room into two parts, only one of which is accessible to the spectator. In the central point of this wall, there is a lens which produces a camera obscura image on the other side. The image fits exactly on the opposite surface on the spectator’s side (floor to ceiling, wall to opposite wall...). The space one enters is, therefore, an (upside-down) image of the other side. In addition, there are small holes in the diving wall to which are attached sandblasted plastic balls with lenses that focus and reflect camera obscura images from the other side on their own surfaces. A couple of these balls reflect a real-time video image of the spectator’s side, and because this side is an image of the other side, the spectator sees himself simultaneously ‘being on the other side’ within these balls.
