I could indeed reverse engineer by playing around, but it's unlikely I'd ever be able to independently produce something like that myself if I went down that path. I think both is the best, learn some theory, play around with it, rinse, repeat. That said, what areas of geometry and physics should I focus on? Any good online resources?
