I'm busy researching for a book and I found the following article. I was, at first surprised to see it, but then seeing the Ivars Peterson wrote it, I shouldn't have been surprised. He's so prolific, it's just amazing.
The article show some beautiful patterns made by billiards, a theoretical ball bouncing around (as on a pool table) only here the ball never loses energy and the table can have different shapes.
