powdertoy - Man Page

The Powder Toy is a free physics sandbox game, which simulates air pressure and velocity, heat, gravity and a number of other interactions between different substances. The game provides the player with various building materials, liquids, gases and electronic components which can be used to construct complex machines, guns, bombs, realistic terrains and almost anything else. The player can then mine them and watch cool explosions, add intricate wirings, play with little stickmen or operate their machine.

The game also features a Lua API, which allows to automate work or even make plugins for the program.
