i saw on tlc a guy who was paralyzed had chips implanted into his brain and he could surf the net (control the cursor) on a couputer screen with his brain. another guy they were able to send radar frequency into the individuals brain. so you could see radar in his head (potential military applications) and needles to say inconcievable unless you expereince it yourself, as your not seeing a radar as you would on a screen but more along the lines of feel the radar... freaky stuff.DogBoy said:There is already a system i saw on the TV where you use virtual headsets to play pacman. They used a college campus as the levels and the eye piece overlays the 'pips' and powerpills etc. I'm sure someone could dig out the video with some searching.
