My brother, Matt, just e-mailed a link to this interface on the 3M website. Given the multitouch hype at the moment, it’s quite a clever little riff on the theme.
Basically it’s as if you are standing to the rear of a multitouch screen. Your mouse controls the finger movements of the person blurred out in the background and a selection does the old two-finger click-and-drag-larger movement that seems to have become a multitouch standard.
