Have you seen the movie " Mad Max Fury Road ? " If it is not the case you will don't understand this video. This guy constructs a drum Robot who plays like the crazy musician in the movie, yes the guy blind who plays guitar with his four drummers around him when they start to " hunt " Max. If you see what I mean, watch this video the sound is really near of the movie, and the mechanism is really cool ! But I have one question, why he does that ?
