This visual essay presents and reflects on Friction Atlas—an ongoing design project that engages both critically and playfully with the spatial presence and implications of law in urban public spaces. Through spatial interventions on public surfaces, the work appropriates and visualizes the omnipresent scripts of law that, drafted onto our public bodies, regulate public assembly and behaviors in urban space. Through performative actions, such codes are then made physically discernible. Law imprints upon flesh a quiet definition of movements and gestures, unconscious reactions, behaviors and anticipations. Pushing the limits of representation, Friction Atlas turns these dynamics into a conscious, participatory choreography. What happens when we redefine the rules as the visible surface of a playing field?
