Check this little gadget out. It's a hand-motion-tracking device for your desktop. Minority Report gesture type for everyone (with out the gloves)! The future is really bright for devices like these and a lot of people would want to just sit back and control their device just by waving their hands around! We will definitely see a lot of them out there and awesome software to do stuff with them. (Hm...3D Studio Max with Leap Motion support. Might start 3D modeling again if that happens). The company that makes it will start shipping them early 2013 and they already take pre-orders. If you're also a developer you can apply for an SDK on their website.
