Recently, a growing number of artists and designers are producing interactive artworks equipped with mobile and wireless communications devices, including mobile phones, PDAs and laptops, connected to computer networks and location-based systems. These artworks are mapping new forms of flow that accumulate invisibly in space in layers of our technological living, and are bringing to light a new urban configuration - the wired city. This new concept of city relates everyday actions to collaborative processes created by networked mobile communications and locative media. We present some of these works from two aesthetic standpoints, the first of which is technological sublime. This emphasizes the presence of technology in our lives as a phenomenon on the order of the sublime, of immeasurable magnitude and power, that transcends the realm of human apprehension and is unveiled only by the technology itself. The second reflects a new relation between art and everyday life expressed in the form of a wired urban nomadism. We call it flow cartography - the mapping of pathways and drifts through the city connected with networks and location systems. The two approaches intertwine in a key question: Is the collaborative nature of the artistic creation resulting, in both cases, in an aesthetic of flow? These collective actions involving artists and participants result in a cartography of the hybrid space of flows in the - subjective and emotional, personal and social - networks and territories we live in: a cartography of the everyday flow of life, a sublime cartography.
