...from the point of view of a paralyzed cyclops -- for a split second." But between 1981 and 1983 Hockney scarcely touched a paintbrush; irked by painter's block, he turned to photography to shake it loose, first with a Polaroid SX-70 and then with various popular automatic 35- mm cameras. He would take a motif -- a friend smoking and talking, people around a table, a swimmer in the blue light-dappled water of his Los Angeles pool, an allee of chestnut trees or a green spindly iron chair with pigeons in ) the Luxembourg Gardens in Paris -- and shoot away...
...minutes later the Soviets and their Afghan Communist allies strike back with 120-mm mortar shells that fall on a ridge to the north, sending up great plumes of smoke and dust. Soon, the well-concealed guerrillas begin to lash Barikot with heavy machine-gun fire. Barrage, counterbarrage -- a typical day in the long and ongoing siege...
...newest and most important additions to the local guerrilla arsenal, however, are two highly accurate rapid-firing Swiss 20-mm Oerlikon antiaircraft guns that keep the deadly Soviet Mi-24 helicopter gunships at bay. There are reportedly some 40 Oerlikons now in Afghanistan. In the absence of reliable shoulder-fired surface-to-air missiles, they give the rebels effective antihelicopter weapons for the first time...
John Garang is seated in a dry riverbed, under the sweeping branches of an acacia tree. Around his belt, the tall (6 ft. 4 in.), American-educated leader of the rebel Sudan People's Liberation Army (SPLA) wears a knife and a 9-mm automatic pistol; his thick hands are clasped around the stock and barrel of a Hungarian-made AKM assault rifle, private serial number 000. Suddenly, the stillness is broken by the shouts of 1,000 of Garang's guerrillas passing on their way to battle at nearby Kapoeta, a southern Sudanese town 140 miles east...
...most computer images, each dot, or pixel, on the screen must be mathematically specified. One frame of 35-mm film can require more than 6 million pixels; a 60-second sequence can cost $300,000 and take months to complete. To speed up the process, Catmull and Smith built a special-purpose machine -- the Pixar -- that divides the computational task among four parallel processors: three to control the red, blue or green washed onto each pixel; one to control the pixel's transparency...
