I've found a delightful little comic written on index cards. Each index card shows some mathematic-esque graph or diagram with labels from real life attached. The comic is simple and charming in so many ways, and I laughed out loud when I read several of them. I'm gradually working my way through the archives, and it looks like the author maintains a pretty high quality and a lot of creativity even all the way back to when she started in August 2006.
