What would you do if a mouth on the sidewalk started to talk to you? In this online/street installation, users viewed people on the street with a surveillance camera and typed messages to them which were converted into speech and heard by the passers-by. A www/street intervention. When live and located, "In Conversation" provides the means for two people, one in the street or gallery, and one on the Internet to engage in a live dialogue with each other. The work aims to examine the boundaries and social customs of distinctly different kinds of public spaces - the street and the Internet - each with its own established rules of engagement.
