Recently I've been having a lot of fun making designs using a compass and a straightedge. I wonder if anyone knows what they are called so that I can learn more about them. Thanks!:)

Hi mashka4math;

Welcome to the forum. I think the first people to do that for arts sake were the Arabs, they call it Islamic design or art.

Hi;

You can also Google for "compass and a straightedge art"

To create some really good math art, you need to program it
