I haven’t been following developments with the Kinect closely, but it looks like someone has got it hokked up to his Mac Mini now. Not sure I would want to control my system with gestures, but this sounds interesting as one commenter pointed out:
“Does it change the channel when you give it the finger? That would be perfect for election time.”
It has been discussed in this thread.
