ContextFree is a helpful (in the right circumstances) and amusing little (free) app that creates errm... well, it's up to what you can make of it. It workks by applying ruls (which you can define) recursively. It can create patterns, textures, height/displacement maps, and it has a very simple interface. But it's rather limited (unless you have endless time to play with it). Can't remember where I got it - try google.. Cheers, Diolma (who must remember to get back to ContextFree ...)
