Aluminium frame, aluminium disks, bearings, electronic motor, rubber belts, spotlight

 

Sixteen aluminium disks are arranged in four columns inside a free-standing aluminium frame. The disks in each column rest on top of each other. The bottom disks are connected to each other with rubber belts. An electronic motor connected to one of the bottom disks makes them all rotate. The shadow of the rotating disks is cast onto the wall behind the work.
