If you remember well about the MTMini project, which used a DIY multitouch platform with a computer and a camera, you will find this very similar. In fact, Sittiphol Phanvilai, the famous MobiTubia developer is basing himself in that same application to create this platform on a Nokia N95.

There has to be a lot of work done, so I guess his work is in a early stage. I mean it can't be easy to incorporate a complex application on just a phone. Enjoy the video and let us know what you think about it, and what you think it can it be used for in future.
