Flowsnake

Not much time for a post today, so thought I’d share something I was working on last night:

Kind of an old fractal classic, known colloquially as “Flowsnake” when it was written about by Martin Gardner, and also as the Peano-Gosper curve. The gosper curve at the border bounds the inner fractal so we can get the nice blue dye effect. I did this with a single L-System so I can generate all different sizes of the two curves, while still keeping them inside each other. Enjoy!
