Falling Sand Game", also "World of Sand",
(2005) is a Java applet first found on the Dofi Blog. The game involves
four main falling particles: sand, water, salt, and oil. Each of these
particles have special properties that can be manipulated; among these
include burning, desiccating, growing, eroding, and more. Along with these
four, main particles are auxiliary environmental manipulators: Wall, Fire,
Plant, Spout, Cera (or wax), ???, and Eraser. By putting these together,
one can thoroughly enjoy the modeling and construction of very complex
structures and systems. There is an additional special feature that can
be turned on, off, or told to remain in place. This is called the namekuji.
In japanese, "namekuji" means slug, naturally for the properties
of a slug when salt is poured onto it.
