Cellular Atomata Physics test

This is an attempt at making a sand physics game there are many materials at your disposal to do dumb stuff with.

Wood - A flammable material that does not simulate physics

Grass - A very flammable material that grows when water is added

Stone - A almost indestructible material.

Acid  -   A corrosive material that can dissolve stone dirt and sand

Sand -  A powdery material

Oil -     A highly flammable liquids 

 Water - A liquid that can turn lava into stone

Lava - A hot liquid that can burn and melt many materials 

Ice - A material that can be melted with lava of fire

Fire - A thing to burn stuff with

Methane - Flammable gas 

Clouds - The clouds are various gasses that can make water,  snow, acid rain, or lava rain.

Controls are scroll wheel to change materials, middle click to clear, and enter to pause.
