510, this is the number of dead eyes suspended at various locations in Poznań. Unnoticeably, these cameras record millions of hours of the city as its invisible witnesses. On 27 June, the cameras will come to life and be visible for twenty-four hours. A camera composed of eight observers will move around Poznań recording the nature and dynamics of the urban fabric. The living camera system will make it possible to observe events from a distance, and to directly record them on paper. Eight pairs of eyes will watch over the city life.
