For Neil Harbisson, a self-described "cyborg" artist living near Barcelona, Spain, colour is quite literally music to his ears, thanks to an antenna he designed to overcome colour blindness.

Well-known in Spain and with an international following that enabled him to meet the likes of Leonardo di Caprio and Tom Cruise, Harbisson is now testing out a new device designed to feel physically the passing of time.
