Wii's Unrevealed Potentials

It was about a year ago when one of my friend forward me link of Johnny Chung Lee's Wii project page. Lee was a Ph.D Student at Carnegie Mellon University but now he is researcher with Microsoft (acording to his website). Anyways year ago he did come up with Head Tracking for Desktop Virtual Reality Displays using the Wii Remote. In simple words head tracking with wii's remote. He has explained his experiment in this video below: I just happens to visit his page again and found out another interesting experiment. This time he is tracking his fingers with wii remote. you can watch this experiment in the below video. You can visit his home page for complete instructions and how to conduct these experiments by yourself. These are really simple and easy. He has used simple software which is required for both these experiments and can also be downloaded from his home page.
