I would love to have a CanvasFilter that makes your smooth 24 bit procedurally generated gradients look like they've been error-diffusion dithered to an 8 bit web safe color palette. And with a FatBits option to compensate for retina displays. Now THAT would be fashionable!

Do you mean the gradient's output should look like it's been put through a risograph printer? I created a CodePen demo a while back which attempts to recreate that sort of effect - https://codepen.io/kaliedarik/pen/RwgwpyG
When it comes to reducing a palette from (potentially) millions of colors down to a set of 8 bit web safe colors - I'm not convinced such a process can generate decent output for a wide range of different inputs. I get much better results by generating a "commonest colors" palette with a minimal distance (in LAB color space) between each selected color to generate the most pleasing dithered output, whereas restricting the palette to web-safe colors limits the output to just a handful of those commonest colors. See an interactive example of the filter here: https://scrawl-v8.rikweb.org.uk/demo/filters-027.html
Oh I wasn't looking for decent output, I LOVE the pixelated error-diffusion dither effect, especially with an ugly garish color map that brings out all the jiggly artifacts. ;)
Oh, nicely done! Trying to code up cellular automata simulations are pretty much guaranteed to push my brains through my nostrils - I've never progressed far beyond classic Conway. Your CAM6 library[1] may be about to steal my weekend from me!
