About

A classic falling-sand simulation. Drop powder, pour water, spark fire, and watch elements interact in a pixelated sandbox. Sand sinks through water, lava turns rivers to steam, acid dissolves everything in its path, and one spark can set off a chain of gunpowder explosions. Draw, erase, experiment. There are no goals, just physics and chaos.
