I spent the first two weeks of my vacation locked in the studio with a pencil in one hand and a heavily caffeinated beverage in the other. The result was an inch-thick stack of drawings for a presentation on biomimicry.
Here are a few sample drawings (out of about 60 total).
You can see the finished presentation at www.designfromlife.org. Not all of the drawings made the final cut, but that's normal for these things, especially when you have to edit for time. It was a fun project with a brilliant group of people, and a great way to start my summer.
