At a one-week residency in Limbo, Limbo, Limbo in Peckham, we brought together different elements. The rule was we would add one element after the other, chosen in alternation by one of us, keeping going until we felt nothing more should be added. We put Mobile Sculpture on wheels, took it to the street. It became part of the environment that had surrounded its making. To this day we still often work this way, taking over from each other. This allows for chance happenings and forces us to explain our decisions to one another.
