Wireless peer-to-peer network technology enables new types of collaborative practices among people in public space and across multiple locations. BashoCam is an on-going project that designs for a collective aesthetic practice across wireless peer-to-peer social networks. It aims at enabling users connected by a social network to create collaborative narratives by juxtaposing rhythmic sequences of photographs taken on the spot. These narratives evolve as they spread throughout the network. We describe the concept of BashoCam, the user interaction and our current implementation.
