Vector enthusiasts, especially fans of Rasterbater, should head over to the Evil Mad Scientist Laboratories website, because they've released StippleGen. It does what Rasterbater does, and a whole lot more.

I haven't tried it yet because my tethered polargraph is nearing the end of a marathon print and I'm afraid to mess with unknowns on my computer. What I see on the EMSL site has me drooling, though.
