BRISTOL LAKE, Calif., May 15 Travelers on Amboy Road in California's Bullion Mountains stop and stare at the light display swirling across the sky, which is what Helena Bongartz wants.For a little more than a year, Bongartz has been putting on the ethereal show for anyone driving, The Press-Enterprise in Riverside, Calif., reported. Every weekend she makes the 30-mile trek -- weather permitting -- from her Wonder Valley home to an abandoned house near Bristol Lake so she can synchronize projectors that cast the colors, patterns and abstract imagery on the outside of the building.A photographer, Bongartz said she began creating sculptures from pieces of large plastic bottles. She photographed them then created animated videos that, generations later, became the abstracts projected on the building, the newspaper said.She first tried projecting the videos on rock formations in Joshua Tree National Park. But it didn't have the traffic she wanted. She tried -- and didn't like -- an elevated water tank.Eventually Bongartz focused her projectors on the abandoned house."People relate to a house in a way that they don't relate to a tank or a rock," Bongartz told The Press-Enterprise. "It has a personality. I had someone drive by and yell, 'Don't look at me that way!'" Copyright 2007 by UPI
