Perpetual Motion

This is a spatial Bricard 6-Bar linkage that can be made from card stock, best sliced by a laser cutter like the Epilog Zing. ( http://en.wikipedia.org/wiki/Raoul_Bricard )

There are slogans on the faces. I originally designed this cardboard toy to advertise the Make Lab at our school arts festival called ArtRageous. I called it a mechanical donut, but my more artistic colleagues called it "Perpetual Motion"

Feel free to put in your own slogans!
