If there's a pencil and any available clean surface when I'm on the phone, I am probably doodling. This image is a prime example. Someone told me that recent research showed this was not a sign of inattention, but a way that brains multitask to help them stay focused (?) Whatever. I didn't need justification for my free-style art outbursts, but it's nice to know someone out there is thinking of doodlers as they conduct their scientific experiments.
