A new device called the Leap creates a motion sensing 3D space around your computer so you can interact with it as you’ve seen in Star Trek. The Leap is able to read with incredible accuracy the movements of your hand and fingers or even a pencil, and translates that to actions on your screen. The Leap can be connected by your computer via USB and will be available in December 2012 for the reasonable sum of $69.99.
