This is Neil Harbisson, the color-blind artist you may have read about in “The Real Cyborgs” by Arthur House (p. 921), who wears an external antenna connected to a chip in his brain that allows him to perceive colors through sound vibrations. He is also considered the first person to be officially recognized as a “cyborg,” and is even shown with his antenna on his British passport.© Piero Cruciatti/Demotix/Corbis
