In the interest of not getting much studying done this weekend, I made some icons. Not that many this time, and they're pretty random. The last three are my first attempts at creating patterns largely from scratch, so I'm not sure if they'll be of any use. Feel free to lift them if you'd like to try them as textures, or just further mangle them in a graphics program.
I think perpetualmonkey might like the Hitchhiker's Guides ones. Oh, and the bases for the two Tank Girl icons were screen capped by insolent_angel.
