If you've had your eye on a Leap Motion Controller, the little USB device that allows you to use hand gestures as input to your Windows PC or Mac, and have been procrastinating on getting one, you may be interested to know that it's 15% off today only.
It's a small device, about one inch wide by three inches long, that plugs into a USB port and allows you to use in-air hand gestures such as swiping, piching, waving and grabbing to control things on your computer screen. The device does take a bit practice to get used to, especially on higher resolution monitors, but once you do it's a fun and interesting method of scooting around the screen. There are over 140 free and paid apps in the Leap Motion App Store, AirSpace, so there are plenty of things to check out.
You can jump to the Leap Motion site at the source link and enter the Promo Code "LeapFlash" to get 15% off and free express shipping, but don't delay as the offer is only good for today.
