Installed in a wall of windows overlooking the Delaware River, Karman Vortex reflects the water's hydrological patterns. Hundreds of colorful discs give visitors a sense of the movement and beauty flowing just outside the museum. But the artwork’s swirling pattern is not just an allusion to watery movement; rather, it creates a repeating pattern of swirling vortices, what is known in fluid dynamics as a Kármán vortex street. This very pattern is occurring in the river whenever the water hits an obstruction, from a boat's bow to a bridge pier.
