Metro: The Temporary in the City - Robert Temel

Extract from 'Temporary Urban Spaces' - Florian Haydn, Robert Temel

They are not empty; they are screens onto which something is projected, but they are already contained information beforehand. They can be thought of as photosensitive material on which all the attempts at projection have left traces over time: immaterial palimpsests, so to speak, that nonetheless have a location. The intensity and durability of these traces varies. The question is: which actions can leave behind more enduring traces and how do the city's users become aware of these traces, perhaps resulting in networks of action.
