Have been messing with Jeffrey Scudder 's nopaint all afternoon. The premise is simple: the tool draws on its own, and if you like what its doing, you click 'paint' and it will save that brush stroke. if you don't like it, you click 'no' and it erases the stroke it was doing and tries something else. you can 'freeze' the state by clicking on the drawing, at which point you can save it if you like it, or click 'back' and keep going.
I found that clicking the drawing works very well as a way to stop the tool from 'jumping the gun' as some of the brushes start really quickly after you click no. e.g. ..
this way.. you can be less random with it, and even think about where you would kind of like (hope) for some brush strokes to occur, and just wait for it to happen, and 'paint' after it has happened.
here are a couple of my favorite self-nopainted nopaints from this afternoon:
