Eric's point is well illustrated by the invention of devices for the blind. One such device is a TV camera which drives a bank of vibrating pins. The blind person straps the bank of vibrating pins to his back, and "sees" a low-resolution bit-map image from the camera. The camera is suspended in air from a cable so that the blind person can easily point it around the room. When one such person aimed the camera at a candle flame, he exclaimed, "The flame dances!" Before that time, he presumed that flames had no motion. By the same token, an artist can take an image in his mind's eye and transform it into a painting, a sculpture, a poem, or music. Information-preserving transformations between the senses is a time honored profession. --Barry Kort
