As I think I've mentioned, the original spur to the idea was seeing some architectural students chalk up a life-size office plan in a London square.
Kass has sent me her photos of this event:
"14:25 Outside the Architectural Asssociation, London, in an outdoor room, invisible, but imaginable from the presence of its ground plan, drawn in chalk on the pavement, and from the presence of chairs, and of people sitting on them."Posted by matt at June 27, 2002 09:52 AM
