The Falling Sand Game was the fist of the collection that I found at http://chir.ag/stuff/sand. It was originally created in Japan and the owner of the previously mentioned website enlarged it and hosted it on his own site. I used the java applet to get a copy for this website.
Using the Falling Sand Game
If you have never played this game before you'll probably be a little confused with the beginning appearance; e.g. a big splobby thing rolling around and streams of different coloured stuff coming from the ceiling. Fear not! This game is amazingly addictive when you know how to use it.
At the bottom of the game window there is a small grey rectangular area with things like wall, fire, ??? etc written on it. This is where you can select materials to draw.
Here's some info on the materials:
The wall is the basic element for the Falling Sand Game and it's recreated versions. It can restrain other materials but can be destroyed by the Namekuji (see below). It can also be charred by fire.
Fire can burn stuff (wow!). It can also destroy things like wall but can be put out by water.
Water is most interesting when used with plants, and can make quite cool effects. If used enough, it can put out fire.
Plant is a green creeper type thing which grows when it comes into contact with water. It can act as a good fuse when burnt.
Sand is another basic element. It doesn't do much but can be fun to wach run down tracks made of wall.
Not to be confused with sprout, as many people do.. This is a material which creates water to rain down on whatever you want. It is good for making greenhouses e.g. draw a house with wall, line the ceiling with spout and put a bit of plant across the floor. Watch the effect!
Latin for wax. It has the same properties as wax: it burns slowly and drips some of its contents which can be caught and solidified. Makes nice candles.
No one knows quite what this is. It seems to destroy nearly everything on the screen, sparing plant. If it is drawn too much at once it can recreate itself, making an endless loop of pink waves...
Another flammable substance and my personal favourite. Oil can be collected and burned to create pretty cool effects.
Guess what? It erases any material on the screen!
Salt doesn't really have a use, except for shrinking the Namekuji, which has quite a cool effect when it explodes...
Thought to be Japenese for slug, the Namekuji is the strange yellow thing that is moving round the window. As with a real slug, it likes water and detests salt. In water it swells and can take over the screen. If it does though, just add some salt and it should come back down to size.
But what are the other settings for? There are a few more options to the left to control various aspects of the game. The first, pen size, is used for setting how big the line is with which you draw.
The time speed determines how fast the game runs. The fastest setting is 5, and setting 0 freezes the window, which is useful for taking screenshots.
Then we have the flow controls: Sand, Water, Salt and Oil. Each one sets how big the flow from the top of the window will be.
Lastly, there is the Namekuji control. This determines the behaviour of the Namekuji: Move, Stop or Vanish.
Finally, just have fun and let your imagination take over!
