Light and space are in an inseparable but invisible connection (theory of relativity). They imply a seemingly stable framework of orientation in everyday life, in which there is no reason to question the relationships between subject and object, cause and effect, beginning and end. At the same time, they offer levels of experience in which these distinctions dissolve into border areas, in which you can no longer cling to the accustomed conditions. The installation wants to open such ambivalent levels of perception and explores how spatial-acoustic installations can influence states of consciousness. A mirrored ceiling, a thin reflecting surface of water on the ground, and a grid arrangement of lights create the spatial illusion of an infinite vertical space of light and darkness. Visitors can cautiously discover the endlessness beneath their feet and above their heads by traversing a small bridge. The extent of the infinite vertical space changes through the individual viewpoint so it can be fathomed by the viewer’s movement in the freely accessible installation.

The acoustic dimension of the Shepard sound complements the installation. The Shepard scale is an acoustic illusion of a seemingly infinite rising or falling scale. In addition to the perception of an extraordinary experience, the installation explores how far a spatial-acoustic installation can influence states of consciousness and how contingency (Luhmann) and slight forms of trance can be experienced. It involves a similar ambivalence in its positioning as the boundaries of perception it refers to. On the one hand, it analyzes analytically objective phenomena and makes them subjectively understandable; on the other hand, it also creates insecurity of perception and slightly touches unreal areas of experience such as “magic,” dreams, and intoxication.
