In the tactile world, we use our five senses to take in information about our environment and respond to it, Maes explained. But a lot of the information that helps us understand and respond to the world doesn't come from these senses. Instead, it comes from computers and the internet. Maes' goal is to harness computers to feed us information in an organic fashion, like our existing senses. The prototype was built from an ordinary webcam and a battery-powered 3M projector, with an attached mirror -- all connected to an internet-enabled mobile phone. The setup, which costs less than $350, allows the user to project information from the phone onto any surface -- walls, the body of another person or even your hand.

Holy crap.

dude honestly insane
