Maptor is this wonderful combination of a map and projector that (predictably) projects the desired map onto any surface. Palm of the hand, floor, and walls included. What I really fancy about it, is its size. Small enough to pass off as a lipstick (or a chapstick for you guys), the device is discreet enough for you to quickly hop into a quiet corner, check for directions and make your way forth. All this without anyone knowing that you are lost or need help!
