Neil Harbison: Life in the age of new body parts and extra senses: https://livestream.com/accounts/6779986/events/2928486/video...

Neil is completely colour blind; he sees no colour at all. So he implanted an antenna on his skull that detects the information he choses (like colour) and converts it to vibrations on his skull. So not only can he now perceive colour, he can even perceive more colours than regular humans, since the antenna can be augmented.
