'90 was sited at The Headlands Center for the Arts, Sausalito California,
March 3-21, 1990. It was a dawn to dusk day of performances, and events. Turned
on by a solar switch at dawn and off at dusk, a large suspended light sculpture
acted as a metronome throughout the day projecting light images into the installation.
The windows projected rainbow colors of sunlight from diffraction gratings and
nori sea-weed as it photosynthesized from green to violet. Messages arrived
by fax, mail, performances and events throughout the day.
