As the emphasis of the technology industry moves from human-machine interactivity towards self-replication, like in bio-, nano- and robotic technologies, art producers are paying attention. Reactive Art, a new exhibit hosted by the San Francisco Media Arts Council at SFMOMA, attempts to take on this seeming paradigm shift. Defining our relationships with technology as an ecological system, the artists in the show present environments that both adapt to, and manipulate, the viewer's own actions and experiences. There will be a discussion with the artists - Crevice, Jim Campbell, and Scott Snibbe - on Saturday, January 25. - Ryan Griffis
