I've been lethargically trying to purchase a Wii for months now, without success. Apparently you have to be quite serious about hunting one down because they're sell out everywhere that they crop up. Amazon.com reported that when they had them in stock, they were selling 17 of them a second! If the technology in this clip starts to make it mainstream, we're going to continue to be constrained on these puppies. The clarity of the description of the technology, as well as the demonstration itself, is first rate.
Make sure to check out Johnny Lee's other Wiimote projects.
