A collision simulator designed to compute the digits of π, inspired by this 3Blue1Brown video. By default, the simulator will calculate 7 decimal digits of π by using a block with a mass of 1 quintillion kilograms.
To calculate more digits, increase PI_PRECISION_VALUE to the number of digits you wish to compute. Change PHYSICS_ITERATIONS to modify up the number of collisions computed per frame - I recommend keeping it below 15,000 to maintain a reasonable framerate.
Simply install pyglet before running:
$ pip install pyglet
