A quick mention of an interesting organization. The Sculpture Center has an exhibit called University of Trash. The goal is to create a forum for the exchange and fostering of ideas about radically rethinking how we live in our urban environment. To this end, they've had artists create interior architecture to reflect a new vision of public city space. Information about self-sufficient and self-organized urbanism is freely distributed (I picked up a copy of Indypendent Reader's "The City from Below" issue). Free classes on do-it-yourself art, and grass roots politics are offered throughout the summer, and anyone can sign-up to teach a class that fits the theme.
