Berg, Jones & Sarvis' site-specific pieces for large groups occur in trees, on rooftops, in stairways, and in schools, parks, stadiums, plazas, and public buildings. They have over a decade of experience making pieces for groups of 30 to 80, often using objects such as power tools, fun noodles, chairs, blankets, oversized physical therapy balls, and squirt guns and wading pools. They will do anything with any number of people—anywhere.
