Good gracious, the Leap will eventually lead the masses to say hasta la vista to the keyboard and mouse.
The Leap is as futuristic as they come. It looks like something out of Minority Report and it creates a 3D interface to interact with your P.C and control software. It is super accurate and it identifies items in your hands like a pencil for example. Control easily comes from the movement of your digits.
Because ingenuity does not have to be complicated, it is a simple case of plug-in and good to go. The Leap will retail for $69.99 and a limited number are currently available for pre-order at LeapMotion.
