Polygon Artwork - SierraKen - 07-12-2022
I made this as an inspiration to B+'s a few years ago. It shows 17 different polygons in order, in random color, layered in giant circles. It changes every 2 seconds and loops back to 3 sides after 20 sides. Thanks B+ for helping me get this far.

That's really impressive B+. Would make an awesome screen saver.
