Due to what are probably very good evolutionary reasons, doodling helps some people concentrate. I'm one of those people.

On Friday I went to CSS Conf EU and, true to form, doodled my notes. I find it also helps if I draw a little cartoon of the speaker. Although they may be of no help to anyone, here are my notes from the conference. I don't claim they are complete or accurate but I can say I had quite good fun drawing them.
