Within the panoptic architecture of the installation this reduction is expanded to the audience (s. sketch). The composition consists of three successively arranged rooms, each with an image plane. If the visitor enters now the installation (room 3) it complies with conventional reception of image and sound (loudspeaker only in room 3). Contemporaneously the visitor changes to the position of the observed. This corporal experience grows if the visitor follows in the succeeding room (2) where the sound is to hear slightly. The visitor is situated between the projection and its reflection wherein he is himself part of it. The image appears no longer only immaterial but reveals its material menace. The visual perception is extended to bodily experience.
