The Wind Kaleidoscope — that's what people named the large geometric panels slowly moving in the breeze atop a building framed by vivid yellow metal.

Walking along the Okawa River, a major waterway that runs through the city of Osaka, pedestrians will easily spot the building because it stands out among its decidedly ordinary-looking neighbors.

Located in the central part of the major city, the building was designed by Susumu Shingu, a 79-year-old Japanese artist internationally known for his mobile sculptures that make use of wind, water and other natural elements.
