This fascinating web site tracks the activities of the BMW Guggenheim Lab, which describes itself as "part urban think tank, part community center and public gathering space." From 2011 to 2014, the Lab travelled to New York, Berlin, and Mumbai to explore how people relate to their cities. What is the Lab? offers a great overview of the Theme, People, and Architecture behind this mobile laboratory and Where is the Lab? provides location-specific glimpses at what the group has found. Perhaps most informative is the Multimedia section of What's Happening? Here, readers will find over 200 informative videos and slideshows, including a lecture by Columbia University Sociologist, Saskia Sassen, on Talking back to your Intelligent City. This lecture is just one of the many fascinating finds buried in the depths of this chic web site. Also, don't forget to play Urbanology Online (on the homepage) and create your future city.
