There's a great film version of "The Social Life of Small Urban Spaces" that illuminate Whyte's theories with detailed footage of New York's Seagram Plaza circa 1980. It's a lot of fun to watch, and not just because it offers a filmed version of the people-watching that attracts us to good parks. Whyte's observations and photography also brilliantly illuminate how subtle elements of design — things most of us don't consciously notice — can have tremendous impact on how public spaces are used.
Any Portlanders interested in Congress Square and its future should treat themselves to spending an hour with this film. Enjoy!
