Falling Sand Game: Physics Sandbox
This falling sand game is a relaxing pixel physics sandbox. Pick an element and paint with your mouse or finger: sand piles up in slopes, water flows and finds its level, stone stays put, wood and plants burn when fire touches them, fire rises and dies out as smoke, and plants slowly grow into water. Change the brush size, pause to build a scene, then press play to watch it come to life. There is no score and no timer, so it works well as a fidget toy for kids and adults or as a simple way to show how granular materials and liquids behave. You can save your scene as a PNG.
