Pixel Playground

Pixel Playground is a pixel-based physics simulator. The player can "draw" with various materials, such as water, oil, fire, wood, snow, sand, ice, and so on. Some materials will flow as a liquid; other materials will retain the drawn shape. Materials can catch on fire and burn away, or melt, or freeze. There is no goal; this is just a sandbox.

Controls to draw, erase, export a picture, pause, and reset to a blank slate all exist.
