I met Neil Harbisson in Brighton in September this year when he gave a stunning talk at the Reasons conference. He's a true visionary, who really pushes the envelope. Not only does he perceive colours as single notes but assemblages of colours become chords. So, faces for instance to him don't necessarily look pretty but they sound good (he specifically mentioned Prince Charles, who apparently sounds very pleasant ...). He also dresses in chords that fit the occasion and showed a picture of a particularly gaudy dress he apparently wore at a funeral because it sounds like C minor. This certainly has mostly artistic value for now but it truly expands the way we perceive and make sense of the world.
