Liquid Webtoy

Liquid Webtoy is a fun little sandbox-like toy to play with. Make colorful animated designs using different shades of water, clouds, and magma. Draw walls to stop the flow and pour in some different colors of paint. Throw in some bombs. Oh, and drop in a duck or two too, to liven things up.

Two too to, did I just write that?
