Researcher Johnny Lee’s five minute presentation at the TED Ideas Worth Spreading Conference on Wii Remote Hacks is awesome. Using a standard Wii controller and a home made infrared pen worth $5 he creates a white board. Its also a mutitouch interactive white board system! Total cost $50 in hardware. Then Johhny shows head tracking which costs $10 on top of your original Wii.
