Didn't someone else post a link to a demonstration of the same technology a while back? Only, in that video, it was upright, not a table top, and it was in a conference environment, and the guy demonstrating it also demonstrated a 3D modelling program where he just doodled some lines with his fingers and somehow turned the lines into 3D model monsters.

Would love to find that video now, but don't know what terms to use in the search.

Anyway ... it looks like they came a long way. They didn't have the wireless feature in the earlier video.
