So after the obvious fap joke, we get to rasterbation part.
here are some tools used with Rasterbation:
http://homokaasu.org/rasterbator/ - Takes some time and tedious if your trying to bet something spot on, but prints at full quality, no dots or any of that muck
http://arje.net/rasterbator - What I use, it takes the image and makes it out of a bunch of dots, then puts it into a pdf file, very quick so if you need to troubleshoot like say, getting the correct max dot size number, its good for that, but only prints in those tiny dots, Who needs lines anyways?
Rasterbation gallery, Post your works for them to be added to the OP
My own little bit of Rasterbation
So go ahead! Rasterbate all day long, it's okay, I'm sure no priest or your ultra religious grandmother will yell at you (unless you're using their printer! )
