David Zinn Street Artist
I just returned from a presentation put on by a local artist association where the featured speaker was David Zinn. What an amazing and engaging speaker. Even though his medium is not anywhere close to mine, it was fascinating to hear him speak and the hear his views on art and the creative process.

Here is a short video that touches on some of the things he talked about during the presentation. It is maybe 5 minutes long.
