Pod, Public sculpture in downtown Portland, United States

Pod is a 30-foot (9.1 m) sculpture at Southwest 10th Avenue and West Burnside Street in downtown Portland. Its static tripod base, 14 to 15 feet in diameter, supports a central pendulum of 73 titanium rods that ends in a star fruit–shaped bronze bulb. The rods swing and flex in different rhythms when pushed.

The sculpture was installed in 2002 as part of the Portland Streetcar Project and added to the City of Portland's public art collection. This timing placed it within a broader civic effort to incorporate art into the city's transportation infrastructure.

Locals call the sculpture by nicknames comparing it to a scrotum, including "Satan's Testicle" and "The Nutsack". Michael Powell, owner of Powell's City of Books across the street, called it "wonderful". In 2003 it was included in a walking tour by the Americans for the Arts Public Art Conference.

The sculpture sits at a busy downtown intersection where you can view it freely from the surrounding sidewalks and streets. The moving pendulum is visible throughout the day and offers different visual experiences depending on weather and time.

The work incorporates seven different materials including stainless steel, galvanized steel, bronze, titanium, lead, plastic, and rubber across its structure and mechanics. This material layering is rarely noticed by passersby who see only the outer form in action.
