Last year, around the same time, I looked into quil to generate images with clojure. You can find the code on GitHub. As you can see there, I have no experience with clojure and thus the code is not very readable.
Anyways, I generated some images with random components. The ones I like the most are the "Floating Triangles".
For the "Breaking Triangles" it depends extremely on the colors, I think. I prefer two colors over three.
Below are the earliest attempts. I was first trying to figure out how clojure works and then how quil works.
A circle with differently (but similarly) colored segments was my first sketch.
