HACKER. “Neil Harbisson. Born with the rare condition of achromatopsia, or total colour blindness, Harbisson developed the “eyeborg” — a colour sensor on a head-mounted antenna that connects to a microchip implanted in his skull. It converts colours into sounds (electronic sine waves) which he hears via bone conduction.”
