LITERAL:
Spectropolis projects are wide-ranging experiences from screen-based interactions to audio narratives and physical installations. Most projects will be presented outdoors in Manhattan’s City Hall Park from 12:00 until 4:00 pm October 1, 2 and 3 unless otherwise specified. Spectropolis projects include a portable hearing device that transmits a soundscape responding to immediate surroundings, an artificial flower that indicates the availability of wireless internet activity through luminescent color patterns, a wired bicycle that chalks text messages from the web onto city streets and a computer station for free download of digital art ephemera.
