The sun pulls the planets around itself; the porchlight pulls the moth into its glow…in this North American premiere exhibit, New York-based artists (and identical twins) Doug and Mike Starn explore the fact and metaphor of the gravity of light-a power so vast and universal it is almost unnoticed. At the center of the exhibit is the Starns' 13-foot homemade carbon arc lamp, an impressive structure serving as both a central work of sculpture and a scientific experimental device that illuminates with its blindingly bright light the installations around it.
