we're not so far away from what Archigram were examining in the 60's. Behaviour and information as the raw material to design cities with as much as steel, glass and concrete.
The city of the future increases its role as an actor in our lives, affecting our lives. This of course, is a recurrent theme in science-fiction and fantasy. In movies, it's hard to get past the paradigm-defining dystopic backdrop of the city in Bladerunner, or the fin-de-siècle late-capitalism cage of the nameless, anonymous, bounded city of the Matrix. Perhaps more resonant of the future described by Greenfield is the ever-changing stage-set of Alex Proyas' Dark City.
