The endotic is a subtle but powerful tool to generate a situated practice of an institution. It is subtle because it looks to the imperceptible of the everyday life, to the visible but hidden details of the space and gestures of bodies around us. It rescues the astonishment from the forgotten obvious, trapped by its naturalization. It is a powerful tool because it leads us to read and listen to our surroundings, always looking from unexplored stances. From this immanent display, the very local traces a priceless threshold from which to approach the complex global. In its well-known methodology, Oulipo—the group to which Georges Perec belonged—was a great pioneer of crossing knowledge fields in order to practice a critical fascination. They developed a system in which constraints were an efficient driving force, merging mathematics, literature and artistic positions. These constraints can be translated from writing to cultural practice to think about spatial design, funding or ways of cooperation, looking for more sustainable practices.
