Any combination of garment, vehicle and house at once.  A non-specific site or ever-changing site requires a highly adaptive system.  I am inspired by exoskeletal organisms, particularly the defensive balling up of wood-lice.  The project is only self-sustaining as a vehicle--and even then it is a temporary condition.  It must at times join roaming cooperatives in order to refuel.  I imagine the vehicular unit comprised of repetitive elements that can be decomposed and recomposed along with other units to form these improvised or emergent cooperatives.
