Above the propelled motion and arcing energy of skateboarders, a tall assemblage of found objects spin and turn in the wind with similar physics. At closer view, these colorful objects reveal familiar Prairie Village street signs, skateboard decks, axles and wheels, and layered traffic sign fragments. The 22 foot tall Harmon Skate Park Sculpture, a.k.a. the Windmill Sculpture, was designed and constructed by Rhett Johnson in 2005.
