*gardener's note: I think that this tweet exemplifies what I liked most about pico-8. I wrote this while tuning out a Zoom lecture on Newton's Law of Gravitation in my highschool physics course. In ~an hour I was able to get a satisfying visualization with some basic mathematical backing, without once having to fight some stupid ass low-level display library.* |
