Gorgeous! I'd never heard of these before.

Impressive — thank you

Very cool! Here’s a fork where I added some color inputs so you can play with the colors, and I defaulted to CYMK which I think has a nice synthwave/cyberpunk aesthetic: https://observablehq.com/d/af95f28e8796f8d6

Looks very good :)

I need to implement a new sampling method. The current one is very fragile and looks bad when you increase max reflections.
