very very cool! At some point i want to dig into how to write physics simulations, in the mean time i'm slowly working on trying to make better numerical computing tools, which is sort of a precondition to playing with simulation.
Oh, man. My previous experience in building simulators is a spaceflight simulator I wrote at the beginning of the year, because space, life is easy and I didn't have to really write hard numerical computing code. This is easily the most challenging thing I've ever written (but it's also easily the most fun thing I've ever written).
Good look getting into writing physics simulations!
