What do your doodles reveal?

Doodling is often seen as a rather rude thing to do whilst in front of someone else. In the past it has been taken to mean that you are not paying attention to the conversation. However, recent research turns this idea on its head and shows that doodling whilst listening can actually aid memory recall.

Plymouth University conducted the study and the result was that doodlers tended to remember almost 50% more detail of a phone message than the non-doodlers.

But what do you doodle? Linear shapes like squares and cubes? Overlapping circles or wavy lines? Flowers or other natural objects? My recent doodles have included arrows and cubes.

I know graphologists will offer to interpret character traits from handwriting styles but has anyone done something similar for doodles?
