Parallax Beast

If you want to print and make your own parallax beast, here is where you can print it from.  Because the faraway parts appear to move slower than the closer parts, it gives the illusion of turning its head.  It was inspired by the work of Jerry Andrus to  to celebrate  the Gathering for Gardner (Martin Gardner, that is), January 16-18, 1998.  Now we are using it for fun and for PHYSICS!
