'Field of Light at Sensorio' by Bruce Munro

Artist Bruce Munro was camping at Uluru (aka Ayers Rock) in Australia in 1992 when he envisioned the art installation on today's homepage. Titled 'Field of Light,' it's currently on display at a venue called Sensorio in Paso Robles, California, the latest stop in a tour of sites around the world. At Sensorio, a new arts center that bills itself as representing 'the intersection of art, technology and nature,' visitors will find 58,800 solar-powered spheres, lit by optical fibers, that change color. When the sun sets, the fibers illuminate, creating a shimmering, interactive landscape in the meadow. The art installation changes a bit at each site, but Munro tells reporters, 'The one constant is that it does make people smile.'
