At just $70.00 this could be a revolutionary tool for interaction at face to face marketing events.

The Leap web site says it is more accurate than a mouse, reliable as a keyboard and as sensitive as a touchscreen AND it tracks the motions of each individual finger in three dimensions.  

They have a developers kit so that you can program interactives and media to work with the Leap.  And amazingly, it is tiny, about the side of a flash drive.
