The increasing accumulation of people in living machines without history and the challenges presented by migration and the lack of space provoke a need for new thinking and acting in public spaces. SUPERSUIT is an interdisciplinary experiment at the demarcation between people and space. It is a tool for poetic interventions in a range of different urban situations that invites participation and queries the relationship between people, space and city in terms of sense perception. As a marker of public space, the spontaneously arising forms of SUPERSUIT respond directly to the parameters of urban context. Using the means of ‘performative interventions’ SUPERSUIT facilitates a change in current design processes and the conceptualizing of new people/material constellations.
