Here is a link to a brief Art 21 segment about Mark Dion's public ecological project in Seattle: http://www.pbs.org/art21/artists/mark-dion
Also, here is a link to Mildred's Lane, Mark Dion's long-term project with (I believe his ex-wife) artist Morgan Puett. The two have created an art/life integrating "complex(ity)" in PA.
"Mildred's Lane [activates] connections that situate themselves at the nexus of science, methods of living, environmental activism, transhistorical and critical artistic practices. This unusual situation affords participants the ability to collaborate in the production of large-scale, socially charged, research- driven projects within a truly transdisciplinary environment. Woven into the project work is a curriculum based on creatively and experimentally living and working together - what we call workstyles. These valuable collaborations are designed to become shared experiences that hope to have transformative and lifelong effects on how artists think of themselves as practitioners functioning in the world."
