So pretty much you have 2 blocks in a zero friction world. If the mass of one block is 10 to an even power it will calculate a certain amount of digits of pi. It only uses the collision of the wall cuz if I do the player it glitch's out. So if you get 3.1414 it actually worked it just touched the block last and not the wall.
