This new device lets you control you computer with 3d movements of your hands. Pre-order leap for just $75.

The Leap technology is 200 times more accurate than anything else on the market — at any price point. Just about the size of a flash drive, the Leap can distinguish your individual fingers and track your movements down to a 1/100th of a millimeter.

Setup is just as intuitive. Plug the LEAP into a USB port. Load the Leap Motion software. Do a quick wave to calibrate. That’s it. In minutes, you’ll be able to interact with your desktop using natural hand and finger movements.
