I've heard about this. If and when these things reach the general public, what a breakthrough that'll be! When I first heard about these, the first thing I wondered was: wouldn't people using these kinds of implants be considered cyborgs? I mean, they are controlling the electronic limbs with their minds. Adam Montandon, user of the "eyeborg", considers himself a cyborg, but I don't agree since he doesn't actually control his device with his mind. It's just a machine he wears on his head and listens to through headphones that tell him the colors he's seeing via codes he can hear. It would be another story if he had an implant in his brain that made him see in color.
