Changing the location of the camera doesn't exactly make it completely different .The lack of a need for finger caps is nice, but that purely means it's a refinement of an existing piece of technology. The slashdot summary just made it out like a completely new idea when it's already been done. I admit, it's a great piece of tech and a much needed advancement from what was done at MIT but it's not a new interface being born.

I'm pretty sure I saw this absolutely ages ago. It was an open source project so you could do it yourself and it was just a projector and a camera on a thing around your neck. The video had them playing a racing game on a piece of paper, they turned the car by tilting the paper. In fact, I'm going to find an article. http://www.wired.com/epicenter/2009/02/ted-digital-six/ There, already done by MIT.

Backlash made them rethink it? Or just pretending to go back on it, to reveal it all at the last moment again?
