Spark visited with Gatti as he explained his intent behind "ONE: An Earth Installation," which ironically happens to be composed without using a single living organism except for a small grouping of cattails. His inspiration for this exhibit came from his reverence for nature and admiration of Native American culture. Although Gatti has spent years building a name for himself within the San Francisco social scene, "ONE" marks his first public exhibition. However, Gatti is no stranger to the public art world either since he served as the president of the San Francisco Art Commission for nine years, starting in 1996.
