Geometric light shapes were projected in random order through the revolving glass plates onto a wall of the Kunsthalle. The resulting constellations of shapes were also reflected several times. Mischa Kuball regards this work as both reflection upon and a reference to earlier works and to the *Light-Space-Modulator* by László Moholy-Nagy.

Geometric light shapes were projected in random order through revolving glass plates onto the walls of the shaft tower. The resulting constellations of shapes were also reflected many times. This was the first time the installation was shown outside the context of a "white cube." The horizontal lines of the shaft tower balanced the vertical direction of the space.
