Maybe you have seen a lot of those augmented reality sandboxes before, but I assure You that this table is way better than everything you get in touch with before. The reason for this is a very high framerate and fast calculation. The project was done entirely in Unity 3d.

The general Idea about a interactive sandbox is already old. You hook up a projector with a microsoft kinect and place it above a sandbox. If you change the sandtopology the projection will adjust accordingly to the new topology, thanks to the height information of the kinect.
