Pattie Maes from MIT has developed a portable device with a camera and beamer that is able to capture information from the environment and project extra information on it while you're wearing four colored markers on your fingers. This video is full of interesting examples where this could be useful, but especially the example where you're just walking on a bridge and put your fingers in the air making a 'photographic' gesture, which then snapshots the environment in a picture... That's awesome.
