Wow this is extremely cool/impressive, but if my manager asked me to implement this I'd quit lol. The "state" headaches alone seem like a nightmare, nevermind all the whacky linear algebra you're going to have hand-roll (Like does Postgres even have a matrix type?? Did you have to implement matrix inversion in SQL from scratch?? I get nauseous just thinking about it.) edit: I guess in 2D a lot of this becomes simpler than in general high-dimensions.
