one of my favorite things to do at the zoo is to watch the polar bears swim. once while we were there a polar bear was doing laps back and forth across the pool--front stroke in one direction and the back stroke in the other. saved him the effort of turning around i suppose.
i drew this picture at work over several days during several teleconferences, hence the blue lines in the background. i thought about cleaning the picture up in photoshop, but kind of like it this way.
