"Everything is its own reward"
– Paul Madonna
There's a free show downstairs at San Francisco Public Library through August 23rd, 2009, and I strongly encourage you to visit. This work is lovely to see full-size and up close, plus there's lots of good insight into the artist's process and philosophy.
After spending time with his art and listening to him speak in an older KQED video in the exhibit, I am fairly certain that Paul Madonna might understand better than most people my motivation for and pleasure in my project to walk every street in San Francisco, every block.

Artist Talk event from June 25th is among the content here (but SFPL has unfortunately not caught on to the idea of permalinks for the videos. Sigh.)
