Sandspiel

A falling-sand sandbox. Choose an element from the toolbar, such as sand, water, fire, ice, plants or acid, and paint it onto the screen. Each one behaves its own way: water flows, fire spreads, plants grow, acid eats through walls. There is no goal, just experiments. An open-source game by Max Bittker (MIT).
