Have a look at Dan Roam’s site. He is the author of The Back of the Napkin - which is about how to leverage the power of visual thinking.
His site has some great presentations – doodle on a virtual napkin of course – on visual thinking. Definitely well worth a look.
I also liked how he used the same technique of doodling to illustrate and promote that same idea. Authentic. Fun. Useful. Love it!
