Codifying the map is very important. On a first level we chose to design the map according to a clear-scaled image of the city plan. We transferred on fabric the most prevalent cultural landmarks, public and green spaces, main avenues and railway. The next layer of subjectivity was added by codifying the embroidery. Green symbolises green spaces, grey public space, black private space, and dashed black overground railway. The third codification comes with the input of the workshop participants. Each participant works on a 45x45cm piece of fabric and chooses to place LEDs, LDRs, speakers, buttons and potentiometers, on it, according to where there is -or should be- light, sound, and public input respectively. Thus, we might find speakers, where there are usually riots (e.g. on Syntagma Square), or public input (e.g. potentiometers) in residential areas, where we would like to see more public participation in the commons. The next layering of the map is the design of the interaction between the 12 pieces of fabric, joined in a single map. We are now looking at how local interaction, e.g. pressing a button in a public space, could affect the overall map, e.g. the sound of the railway throughout the city map.
