I wonder what could be a criteria for demos like this that doesn’t devolve into code golf nor spawns giant files.

I’m not saying that to disparage the content mind you; it is amazing. Just wondering which potential rules could make similar results and “normal”/readable code, as that would be awesome to see.

Shadertoy might fit that category? Runs in the browser, are all fragment shaders and without a size limit afaik, but they tend to be small-ish
