People like the pentagons ([url]http://mathhombre.tumblr.com/post/59426811899/pattern-playing-plus-a-little-mathart-is[/url]), so I thought I would extend it, and upload it to GGBTube.
The idea was to make a visual for a rich pattern that would offer an opportunity to model more than one pattern. This one seemed ridiculously rich. I loved how it started off exponential and gets complicated. And that it ends!
If you download the file you'll also have the pentagon tools for making patterns of your own.
