FIRST OFF . . .

Los Angeles Mayor Tom Bradley proclaimed Wednesday “Holographic Visions Day” in honor of the opening of Holographic Visions, the city’s first museum-gallery devoted to the art of holography. Bradley also unveiled a life-size holographic stereogram of himself working at his desk. Made from specially processed movie film, the stereogram is a three-dimensional moving image: As the viewer walks past it, the mayor appears to hang up his telephone, look up, smile and wink. Invented in 1947 by Dr. Denis Gabor (who received a Nobel Prize for his achievement in 1971), holography is a process related to photography that uses laser light to produce a 3-D image. The downtown Los Angeles museum-gallery is in the California Plaza, next to the Museum of Contemporary Art.
