It is very easy to stumble upon public art in Seattle. It is everywhere. We had stack of well designed maps delivered to the gallery of all the public art locations. I am still waiting for it to reveal itself on the web or integrated into google maps. (Did you know google will map out your walking path or public transit for you too? Amazing.)
This is a photo of the Reads by the EMP (Experience Music Project). EMP is a museum, but the building itself is the real feat. Check out flickr photos of Seattle Public Art.
