I had a very slow night at work, sitting in a cleanroom suit, stewing in my own juices with nothing to do and no working internet. I turned out eight pages of random doodles. This gem was the high point of the night when I... still had nothing to do.
I can't remember the last time I put so much texturing down with a ballpoint pen. This is ballpoint pen on cleanroom safe paper. Crap doodle only took about fifteen minutes of work, but it was off and on as I wandered around for an hour and kept returning to my area.
