More for me than you, K, but...OMG! This project is sooo awesome! The Human Mirror, the latest project from Improv Everything. It's the sort of curiously absurd action I had imagined for the heads on the "L" in Chicago. See the full story and their other projects: http://improveverywhere.com/2008/07/06/human-mirror/. Almost an extension of the old flashmob happenings in New York.
(I'm totally J about the cell phone symphony---this was always something I wanted to orchestrate.)
