One of the most beautiful places in St. Louis is the Missouri Botannical Gardens in the heart of the city, consisting of 79 acres of the most beautiful greenery, flowers and sculptures imaginable. In 2006, the Garden hosted an exhibit of glass artist, Dale Chihuly, throughout the Park. These balls were floating in the Angels Reflecting Pool in front of the Climatron.
Here is the same image in black and white with only the floating balls in color.
