Drugs help you doodle

As the next exercise involves doodling I thought I'd browse the web for inspiration. Flickr is a great source of ideas! I found this by someone called kfarewell which just shows had simple ideas can still be pretty and still integrate nicely with each other if done well.

I also found this sketch/doodle by a French artist  Jean-Martin Charcot. Apparently it was drawn with pen and ink under the influence of hashish. If this is what hashish does for drawing skills then I need to get myself a load!!!!
