Erik weihenmayer lost his sight when he was 13. Twenty years on, in Paul Bach-y-Rita's lab at the University of Wisconsin Medical School, he caught a rolling ball, played a game of rock, paper, scissors, walked through a doorway and watched a flickering candle flame. Nothing had changed with his eyes. Instead he "saw" with his tongue. A camera mounted on Weihenmayer's forehead fed a signal into an electronic device that turned the pattern of light and dark into electrical pulses. The pulses stimulated an array of 144 electrodes on a grid about the size of a postage stamp, which zapped the coded image onto his tongue. At first he described the sensation as being like candy pop rocks exploding, but later he experienced something more "out there" in the world - a sense of space, depth and shape.
