this is kind of old, but i just found it again so the upload won't hurt.
jens betha and i built this multitouch table at university in '07 if i remember it correctly. it's kind of a rip-off of jeff han's invention and pretty similar to jens wunderling's design who posted a making-of on his blog. i wanted to try it myself so i made this at university with quite some carpenter-help from jens betha.
tracking and visuals were done in vvvv.
we used a normal DV-camera with an infrared filter so the tracking wasn't the best of all times.
built at the university of applied science in kaiserslautern, germany.
