This MOC has two quidditch teams orbiting each other using a single Lego motor or alternatively a hand crank.
Here is a link to a brief video of it in motion. http://www.youtube.com/watch?v=M4V7aMSo20c
There are three planes or rotation going at different rates with Quidditch players also orbiting each other on their own levels.
I love the Technic sets but I would like to see Lego come out with more sets that emphasize artistic use of the gear sets and automation.
