Curveball (2010) is a public art piece by American artist Thomas Sayre. Curveball contains 30 stainless steel spheres—each nearly seven feet in diameter—arranged to hang from two parking decks. The placement and spin of each sphere represents a sinking fast pitch coming at ballpark visitors from the eastern deck, and an ascending hit emanating from the visitor at the western deck. By day, the surrounding city is reflected unto the spheres. By night, an ever-changing light show projects colors unto the parking deck and its inhabitants.
