Natural Science Lecture Demonstration team, basically a group that makes awesome show and tell things for Harvard, made this amazing pendulum device that from the side angel looks like a huge dance scene. I can totally see people doing this dance. In fact I'll keep a eye out for a version with people.
For now feast you eyes on this. The sequence starts at :27 and lasts exactly 60 seconds, you can see it begin again at 1:27. Amazing.
