„The Crackboxes are “shape-shifters” the form of which inconspicuously follows
the lines, edges, and columns of a performance space. They only become “visible”
when they sound and their cracking sounds move swiftly through the space."
Connected by a cable electromagnetic signal generators are mounted at intervals of
0.50 meters. Close-circuited, they generate a cracking sound. The 32 meter long cable
of the Crackboxes chain can be arranged in various ways. Schläger places the chain
either inconspicuously in the room or he constructs with them objects on carriers.
