Cube in Cube, a projection by G8 Labs

Two cubes are spinning around the same axis, the big one looks empty and transparent, and contains the little one, which seems full and white. However, only the big one is full, the small one is nothing but a 3D-like projection adapted to the big one rotation and to the location of the head of the viewer (detected with a Kinect). This is just a prototype made by G8 Labs, but it looks promising.

Here are other tests G8 Labs team did for their projection on a spinning cube :

(a prototype built with vvvv + Arduino. the system can be controled via iPad or Handwheel. Mapping setup takes less than one hour)
