I bet if you make it `scaled up` and then after drawing it, scaled it down with smooth filtering, it'd look more realistic - ie antialiased. But it's actually not too bad. The only problem with procedural generation is it seems to require such specific `formulas` to output all the different types of possible textures. I think figuring out how to `project` a texture ie create one, rather than to just `absorb` a texture ie perceive on, is quite a new area.
