Animated Box with vertices on circles - based on original work by Dave Whyte from [url]http://beesandbombs.tumblr.com/[/url] 8 congruent circles were drawn; then a point placed on the lower left and lower right ones. The remaining points were created using 3 vectors, since the box needed to have parallelogram faces to match Dave's animated gif. 3 quadrilaterals were drawn representing the top, front, and right side of a box. They were colorized; then the points animated.
It's possible to animate points on ellipses. How would this change the animation?
