OSM Toy ReMake

This is a remake of a desk toy I saw on ThinkGeek years ago ( OSM: Spatial Manipulation Toy http://www.thinkgeek.com/product/15dc/ ) . They no longer seem to sell it, so I thought I'd make my own. Enjoy.

Clip together even numbers of the model (at least 6) to form a triangle or higher order polygons. Now you can rotate it in on itself by pushing the middle disks down while pulling the outer disks up.
