I found this link on Blue's News, where I find everything interesting. It's a program called Scribbler, which takes your simple line drawing and sorta scribbles on it... check it out: Scribbler. Here's a picture I made with it. I probably spent like 3 hours trying out different things. This kind of thing is just plain addictive!
Not much else to tell you right now - I'm working hard on graphics for someone else's game, then I'll delve more seriously into the wonder and mystery of Grimbelina.
