Digital video, computer imagery, virtual reality, holography, lasers and light are among the subjects explored in a new, 7,000-square-foot exhibit at the California Museum of Science and Industry in Exposition Park.
"Liquid Vision: Lasers, Holograms and Virtual Reality" emphasizes learning through participation in creative activities that teach the science behind cutting-edge technologies. Visitors can design a three-dimensional room, compete in a game of "virtual volleyball" or produce, direct and star in a music video in the interactive exhibit.
Los Angeles is the only West Coast stop for the exhibit in its four-year nationwide tour. The exhibit will run through May 1. Call (213) 744-7400.
