Draw a curve, then watch it shrink! Use turbo mode if you're impatient.
This isn't exactly the most exciting thing I've ever made, but I'm happy to have finally figured it out. I learned about this in Multivariable Calculus near the start of the school year, and after several attempts, I gave it another shot today and got it working! Inspired by: http://a.carapetis.com/csf/ Curve Shortening Flow is basically the shrinking of a closed curve based on its curvature. It's hard to explain, so I'll just let you see for yourself.
