The shared use of urban land, newly induced transformed communications capabilities, represents a potentially vast space of interaction. The roads traveled and crossed daily by the community, they tend to become places of direct communication, exploiting the physical potential of being crowded passageways. A rework significant places for personal reasons, sharing history and motivations is Yellowarrow , a system that allows you to publicly report places accessible from the street, through the sticky yellow arrows that will point to. Each arrow is a code and an email address that allows you to retrieve information compiled from his marker, which I shared with the respective user. The system works for now only in the States, but it makes public another scheme of interaction with the physical world to connect personal emotions and places on equal terms, ie without any intermediaries involved. Operations in the territory, whether they are activists , or social and aesthetic , instill a different perception of the same territory in their users. This new consciousness of space, allows you to regain your visual scene greatly downsizing the visual impact of commercial space, and implementing a new key, public and shared with the world around us.
