It must have taken many hours! May I ask where you got the bits of circuitry from? Did you buy broken peices of things and hack at them lol or were they given to you say you were to go to PC World or something and they had no use for those parts?
Only decent photo I have of him, it's really old. He was in an exhibition, and one of the curators dropped it down some stairs and destroyed the internal support structure, so it couldn't stand up anymore. I've been slowly ripping it apart to make new things, to try salvage it.
