192021.org is a promise from Richard Saul Wurman, founder of the outstanding TED Conference, to do a longitudinal research and sharing project focused around the rise of supercities in our world — in particular, the 19 cities that will each have more than 20 million inhabitants in the 21st century. The site right now is a neat flash presentation that I found provocative & that I’m hopeful will lead to interesting work. Worth checking out.
