Like the Kinect, but focused on hands above the desktop.  The video is 
actually really cool, especially at the end with the 3D hands.  A 
comment mentions that the tech used must be able to penetrate the hands, 
since they are showing the top of the hands as well, but (a) it's 
probably smoke and mirrors and (b) they could also just be rigging a 
model of a hand with the info that they get from the sensor... Anyway, 
for $70, it looks like it'd be a super fun toy / potentially interesting 
input method if you do much work in 3D.
