We are not sure if this is very kewl art or terribly wrong. Canadian Rob Spence lost an eye in his teens and now, with the help of some buds, has developed a prosthetic one that can broadcast video and will become a public feed. The device consists of a 1.5mm low-res cam, a small circuit board, video transmitter and a microbattery that Spence says can be recharged via his laptop's USB.
