Colour-blind artist hears colour

Fascinating project by artist Neil Harbisson: 2012 Ted talk

Artist Neil Harbisson was born completely color blind, but these days a device attached to his head turns color into audible frequencies. Instead of seeing a world in grayscale, Harbisson can hear a symphony of color -- and yes, even listen to faces and paintings.
Neil Harbisson's "eyeborg" allows him to hear colors, even those beyond the range of sight.
