Dead Jester Oekaki!
If you don't know what an oekaki is, it's basically an online drawing applet. You draw your picture directly in the browser, and send it so people can leave comments and stuff. It's fun.

A page of brushes I made for Adobe Photoshop a while ago. Most are crappy, but, uhm... download and use them anyway. You know you want to.
