This is what happens when I get bored. Either while at work, home, or "other"...I usually try to have a sketchbook or barring that... papers that I may or may not need again.

Sometimes I get lucky and find a whole piece of paper (or the back of something to be thrown out). Let the doodling begin!

I recommend mindless doodling. It helps my thinking processes immensely. Just blank out, doodle, and let whatever answers you are looking for wash over you. It's like graffiti zen.
