Newegg offers the Leap Motion Controller for Windows and Mac, model no. LM-010, for $79.99. Coupon code "MASTERPASS" cuts it to $71.99. With free shipping, that's $8 under our November mention and the lowest total price we've seen for this controller. (It's also a current low by $13.) The Leap Motion Controller uses the space between you and your computer to track the movement of your hands at a rate of 200 frames per second. It purports to follow all 10 fingers up to 1/100th of a millimeter, making it significantly more sensitive than existing motion-control technology. Deal ends December 21.
