Charles Gaines' installation "Greenhouse" is a smog-conscious microcosm of the city of Los Angeles.


A computer-controlled system of multicolored lights shines down on a satellite photo of the L.A. basin; each color represents a different airborne pollutant. If regional air pollution levels are low, the lights get brighter; if levels increase, they grow dim. Every 15 minutes, the computer receives data from a website that records local air quality and the structure fills with fog, diffusing the lights in a cloud of haze.
