Spanish artist Ana Soler has created a new Visual Art installation called Causa-Efecto (Cause & Effect). Her work is comprised of 2,000 tennis balls hung throughout the Mustang Art Gallery in Alicante, Spain. The balls are carefully aligned in suspended patterns that creates the illusion of the tennis balls are moving, bouncing off the walls, floors and ceilings. The exhibit creates a sense of motion that is rather incredible. Imagine how much time was spent the artist is to capture each of the balls in position!
