I first saw this video when friend emailed it to me with the question, I know its mechanically possible, but is it musically possible?
To me, the question should be the other way around. Musically, the piece is possible, but mechanically, I doubt we have the technology to do this.
But what a feat of animation it is. I'm in awe. If anyone knows where this comes from and/or where I can see the whole thing, please let me know.
