The Children’s Hospital at OU Medical Center (Oklahoma City, Okla.) welcomes young patients and their families to its campus with a scene comprising 12 kites and three bronze sculptures of children at play.

The 140-foot-long piece, titled “Spirit,” is the work of Omaha, Neb.-based sculptor Matthew Placzek and took 14 months to complete.

The stainless-steel kite structures are fitted with acrylic panels and illuminated with 5,000 LEDS to create a colorful and moving display. “It’s a playful scene entering the hospital and is meant to offer enjoyment to the young children,” Placzek said in a release.

OU Medical Center chose the sculpture from a field of 181 national and international entries. It was installed in March 2014.
