What is this?
This is a combination of Conway’s Game of Life and a Falling Sand Game. The interactions of the two are somewhat rudimentary at the moment, but it’s definitely fun to play around with. Check/uncheck the checkbox to turn life rules on and off, choose a material from the select dropdown, and set your brush size with the slider.
