Public Art 2.0: Media, Technology & Community in the Interactive City—A new era of public art is emerging, we call it Public Art 2.0. This issue reveals the cutting edge in innovative and interactive new forms of public art. Guest editor Steve Dietz, artistic director of the 01SJ Biennial (http://zero1.org ) in San Jose, CA, and the executive director of Northern Lights (http://northern.lights.mn ), presents eight feature articles that take you on a tour around the world to explore the convergence of several trend lines creating new and exciting possibilities for the artist working in the public sphere. In addition to the 2.0 section, we take an in-depth look at the field in Illinois (our featured state) and four cities: Portland, Winston-Salem, Greater Phoenix, and Tel Aviv. And there's plenty of book reviews, news, recent projects + publications to keep you in the know about the latest in the field of contemporary public art.
