When I need to, I make mathematical images to improve my mood. For me, it works. These are three I created yesterday, using MS-Paint and Geometer’s Sketchpad.
I have a hunch this sort of thing would only work for a very few people, and we’re probably all Aspies, whether diagnosed or not.
I also call this sort of thing “recreational mathematics.” It’s better than Prozac, at least for me.
I’ve been doing this sort of thing for far longer than I’ve been on WordPress. These are just the latest such images.

It may not work for everyone, but it had worked for many people for a long time. For example, Islamic tiling patterns.
