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.

So what happens when you take the click out of the interface.  Go over here and try it out.  Fascinating experience.

It raises some thoughts for me.

1. Why remove the click in the first place.  I mean it's a ubiquitous, trivial user interface that works. 
2. Removing the click removes the use of our fingers from the device.  You now are limited to your hand and arm...isn't that a downgrade?
3. A lot of the questions and work that went into this site seems devoted to making the non-click interface as easy to use as the click...uh...just keep the click.
4. My subconcious wanted to click SOOOOOOO bad during portions of the experiment it was kinda weird.

Go check it out it's pretty interestingg.
