I need to dig up the code, but over the course of a week on the train rides to and from work, I built a very simple ray-caster in Pico-8 on the Pocket Chip. It was especially fun since I had figured out the math for it on my own (which, in fairness, isn't terribly complex with even a high-school understanding of Trigonometry).

I had enough fun with it that I think it might become my new "trying out a new programming language" test, since it was easy enough to get done quickly, but difficult enough to where I had to actually learn the language.
