Harbisson was born with achromatopsia, a rare visual condition that causes total color blindness. In the early 2000s, however, he teamed up with scientists to acquire an "electronic eye" that senses color frequencies and turns them into sounds. The thing is, it's a device that a doctor drilled into his head. He proudly proclaims himself to be a cyborg.
"Life has changed dramatically since I hear color, because color is almost everywhere," Harbisson explains in his June 2012 talk, "I Listen To Color." "So the biggest change, for example, is going to an art gallery, I can listen to a Picasso."
