(hi 512x512px) (low 256z256px) Generative canvas (javascript,no hydra)

The other night I was thinking what'd happen if I took a parametric equation, compute the max and min values, segment the results in 5 sections matching the colors of a palette and adding some interlacing. I didn't have a clue what it would look like! But now you can see the results, it's beautiful! Every frame is generated pixel by pixel. This is all vanilla javascript. And with some nice rarities.
