At my High School, our senior Art Students would display their major works. My grade's school Captain made a poster of post-it notes. He drew a post-it note everyday of the year. Some hilarious, some the exact opposite. I loved that idea.
The simplicity of the drawings and the idea. Taking a few moments of each busy day to write down a thought. It is such a clear way to document how you were feeling that day.
When I stumbled upon Illustrator Marc Johns, he reminded me of that Art work.
Check out his simple, (naive almost) drawings each interesting in concept.
