Pen plotting. You write code that makes designs by drawing a bunch of lines, and then use a robot (mine is an AxiDraw) that traces it out on paper. In general, generative art (using the pre-generative-AI meaning, i.e. procedurally generating art). There's something really satisfying about writing code in a creative context, because there's often no right or wrong. Often you write a bug, or your algorithm didn't work as you expect, but it looks interesting, and that becomes a new path to explore.
