The setupm from 3Gear, requires two depth-sensing cameras (aka Kinects) at the top corners of your display. Then simply give your computer thumbs up — or whatever other gesture you might feel like — and it'll know what you're doing. The software is available for free while the product is in beta testing, if you want to give it a try. The story also includes a cool video.
