Reply to Leap Motion

Just read about this new Kinect-like device called Leap Motion. I've never really been a fan of these things, but the video really impressed me, and the price ($70 pre-order) really makes me believeing about buying one. Considering its accuracy, it might just be a nifty DJ controller (or rather an add-on), what y'all reckon?

Check out the video here:
