Hey.... I haven't tried it, but this site:
http://www.contextfreeart.org/
has a tool you can download to create graphics by describing them in kind of a programming language. It might be useful for making backgrounds for games, or just weird looking stuff.... Seriously....
Check out these samples to see what it can do:

It was created by someone with the following code/text:
startshape START
rule START {
CIRCLE{}
RAINBOW_SPLIT{hue 0 sat 0 b 0}
RAINBOW_SPLIT{r 180 hue 120 sat 0}
}
rule RAINBOW_SPLIT{
RAINBOW{}
}
rule RAINBOW_SPLIT{
RAINBOW_MINI{alpha -.9 y -.4 s .2 flip 1 b -1}
RAINBOW{}
}
rule RAINBOW{
SHADOW{}
CIRCLE{}
HIGHLIGHT{}
RAINBOW_SPLIT{hue 1.5 sat .1 s .99 b .001 x .09 r 2.8 }
}
rule RAINBOW_MINI{
SHADOW{}
CIRCLE{}
HIGHLIGHT{}
RAINBOW_MINI{alpha .1 hue 2 s .98 x .3 r 2.8 }
}
rule RAINBOW_MINI .04{
SHADOW{}
CIRCLE{}
HIGHLIGHT{}
RAINBOW_MINI{flip 1 alpha .1 hue 5 s .99 x .3 r 2.8 }
}
rule SHADOW {
CIRCLE{hue 3 b -1 sat -.6 s 1.1 y .04 alpha -.7}
}
rule HIGHLIGHT {
CIRCLE{ hue 3 b .7 sat -.3 s .98 y .05}
CIRCLE{ hue 3 b 2 sat -.7 s .9 y .01}
}
and here's the image it creates:
