Each physical city is unique-a signature skyline of geometry modified by geography below and about. It is the virtual city that breaks free of gravitational actuality, coalescing instead into one great net of memories and dreams. Since the advent of immersive media, we can dislocate ourselves from the material city and live inside the vertiginous space of virtuality. This lecture makes a journey through various manifestations of the virtual city, from a brief trip into the film cities of Metropolis, Hollywood, Berlin and St. Petersburg, to the mind trips of Chip Lord's L.A.-Tokyo-Mexico City and Victor Burgin's San Francisco-Marseille-Venise, condensed megalopolises. With Jeffrey Shaw's letter cities of Manhattan, Amsterdam, and Karlsruhe, we decided the path of the story, finally entering the body of one great virtual city in Toni Dove and Michael MacKenzie's Archeology of Mother Tongue.
