Neil Harbisson raises many eyebrows around the world, just by being himself - the Catalan-raised, Northern Irish-born artist is best known for being the first person in the world with an antenna surgically implanted in his skull and for being legally recognised as a cyborg by a government. His antenna sends audible vibrations in his skull to report information to him. This includes measurements of electromagnetic radiation, phone calls, music as well as video or images which are translated into audible vibrations. His WiFi-enabled antenna also allows him to receive signals and data from satellites. Since 2004, international media has described him as the world's first cyborg or the world's first cyborg artist. Gareth gets to know more about Neil here as he explains his new implant on his knee, finds out how he hears colours, his experience of having his antenna hacked, coming to South Africa to speak at the SAS event and donating his organs (including his antenna) once he's dead.
