The current special research study located in the urban tissue, searches another way to look at the city. The observation focuses on eyesight, on the look. The concept of the urban screen, is a construction of the gaze which formalizes the random look through the logic of the frame. Around every imaginary frame new socio-spatial conditions appear which build a different to the ordinary part of urban space, a heterotopia. In these places a reconstruction of the experience of the city takes place, a program’s add through the urban displays. As an urban display we define a visual view, in real time, of the city’s web, a frame which carries the characteristics of a projection screen without acting as one. Who stands in front of those screens? A random person, an ordinary man with a multiform nature, that of a citizen, a spectator, a director, a traveler. The person in front of the various screens, looks, observes, gazes and collects fragments of a moment from the public or private sphere. The experience of the frame offers a visual reading of the city, which differentiates the perception we have of it. Our tour inside the urban fabric changes over time. Temporary cinemas appear and disappear, causing the person to discover and add them to its personal open list of screens. Images and points remain only in our collective memory; offering an informal urban knowledge that will accompany our everyday life. What exactly do we know when we say that we know our city? What exactly do we see every time we see our city?
