I was fortunate enough to to take my sketchbook class to observe medical students dissect donor cadavers. These donors gave there bodies to science to further our knowledge of the human anatomy and to train our future doctors. We worked alongside the med students and anatomy fellows. It was a humbling and fascinating experience.
This is old (2007). I used to work at the ad agency that had the Harley-Davidson account for a number of years. I always carry around a Moleskine sketchbook and take meeting notes on one side while doodling on the page next to it. This doodle ended up being used extensively in the Harley-Davidson "Dark Custom" campaign as well as on a line of Dark Custom Motorclothes.
It say's "FUCK YEAH" in it and they never noticed. :)
