I don't think much of anything would get done in this world if everyone could doodle like Jim Stoten. He's an illustrator living and working in London that seems to have done it all, but what really got my attention, and is most relevant to this site, is the above time-lapse video he did for Don't Panic. Drawn on the fly in under two hours (wow is all I could say). Watch the whole thing, but make sure to pay attention at around the 38-second mark.
