There appears to be some differences between master and my local machines so this didn't work as expected. revert Updated sim.py updated sim.py with performance patch from the dev branch.
Falling Sand Simulation Concept in Python
mostly a concept in python for falling sand simulation i guess the goal is to make a python version of the powder toy which is a falling sand sim the code is not finished yet, but i will update it as i go.
