TED was last month, but this video of Wii savant Johnny Lee went up last week/over the weekend. It’s cool stuff, but the really neat part is how inexpensive the setup is–especially compared to the thousands professionals spend on similar technology. Like Lee says in the video, you pay a mere fraction of the cost of a “real” rig and get 80% of the functionality. If that means a poor schmuck like me can play 3D head tracking games on the cheap, that’s fine by me.
