A large, rocky-looking cube hangs from the ceiling and slowly rotates by itself. But depending on the setting, visitors can also touch it, push it, make it spin faster or slower, swing it...

Sensors are capturing the position of the cube. A projection is mapped to the faces of the cube in realtime.

(This can be done quite precisly. But actaully lower quality sensors and setup are adding some nice 'lowFi' effects for free, so we mostly use just two projection angles, using one standard kinect each)
