Australian artist Nike Savvas built this art piece out of 50,000 polystyrene balls, titled "Atomix - Full of Love, Full of Wonder." A series of 10 blowing fans then "vibrated" the balls and made them appear to shimmer in colors. The installation was part of a sculpture exhibition called Adventures with Form in Space that opened in New South Wales Art Gallery in Sydney.
