I've recently spent some time staring at the contents of the MacTeX Distribution.
Which is how I discovered Toby Thruston's classic, "Drawing with MetaPost".

Procedural drawing with Lua is lovely. MetaPost provides another drawing language that might be considered more TeX-like.
I'm not sure. I tend to be humbled by the TeX community. Inspired.
