This conference looks like something very interesting.
Apparently in the last incarnation, attendees spent the day applying wiki philosophy to home construction. Using some simple materials (fabric, tape, etc), anyone could add or change the community structure. It was described to me as an “octopus-like creation” stemming from conflicting design strategies. Some wanted large, open spaces; others sought to build private, intimate spaces. Ultimately, the project was constrained by the length of the day and the size of the space (some complained about it being a fire hazard).
