The exhibition examines one of the last half century's most pressing and transformational conditions—the overlapping and intertwining of cities, people, and information systems. The informational community can be traced back to the prescient use of computers in the 1960s by the Greek architect and internationally celebrated planner of cities, Constantinos A. Doxiadis, through the work of DACC—the Doxiadis Associates Computer Center. The computation practices in current informational geography in Athens include technical administration, the territorial spread of the city, state border management systems, etc. My role is to research these applications, showing a combination of possible, probable, and actual border trajectories as well the architectures, spaces, systems, and infrastructures that monitor and organize movement at different scales and model them as a catalogue. My main contribution is researching and reconstructing the entire DACC in the courtyard of the Lycabettus Hill office, focussing on their UNIVAC 1107 computer systems and transforming them into 3D-print models and diagrams presented at the entrance of the exhibition space. Efforts are further conducted to model various-scale information collection instruments and facilities spanning multiple state border control rooms and the Hamilton Jet HM422 belonging to the Greek Coastal Guard patrol.
