I'm not sure if this has been posted at DV before...

Check this video out, it's rad! Revolutionary technology that allows you to interact with the cyber-world of information seamlessly, directly with the physical world, using simple gestures. There's less need for your computer, since you basically project it onto the environment around you. Apparently it is processed with your mobile phone (not sure which kind) and the entire "gestural interface" can be optionally made at home.

+ iconic gestures, drawing an icon in the air. Like, Whenever I draw a star, show me the weather. When I draw a magnifying glass, show me the map.
