The site is a steep hill behind which are a series of playing fields.  The blue concrete spheres appear to be rolling down the hill; their movement, color and form offering a sense of humor and playfulness, while their scale (9' diameter) and mass add to their visceral sense of presence.  They appear to emerge mysteriously from a grid of trees planted at the top of the hill.  This is an example of activating a large site, visible from the county road and drawing attention to the play ground and playing fields beyond.  Skyballs is located at Anna Cummings Park in Santa Cruz, CA.  Keefer&Gillman ($55,000) 2001.
