i wrote a gravity simulator. 65536 bodies

once i get the parameters of the code fine-tuned, i'm going to try a one million body, ten thousand timestep simulation

Impressive. Do the edges wrap? Is everything equally distributed or (presumably something caused stuff to start clumping)?

yup, edges wrap, and the force of gravity wraps too (that was a nasty implementation detail). everything starts on a uniform grid with slight perturbations to position and velocity
