We designers have a tendency to doodle on anything from sketchbooks to cocktail napkins. The most gratifying part of this exercise is when free form doodles turn into the beginning of an amazing illustration.

To illustrate this, we've handpicked a few groovy examples we stumbled upon and hope that these will inspire you to come up with some off the cuff sketches of your own. We'll keep an eye out.
