From down the hall came the stutter of machine guns and the whine of planes. "Oh that's our shooting gallery," my guide said. As we entered, two enlisted men on a yeoman's holiday were firing at planes, flashed on a screen by a projector. An electrical apparatus records the hits, while the sound track blares the sounds of battle. "How are you doing?" yelled the Lieutenant. "Little rusty," the sailor yelled back, as a bomb explosion reverberated in the room...
...structure, the film has serious faults. It begins so slowly that for a while audiences can almost imagine that there is trouble with the projector. Even as the emotional rhythm catches hold, the mood is continually jolted by meaningless digressions. Nonetheless, there are several scenes which draw their moral beauty to a point that pierces like anguish. There is the moment on the train when the father gives the boy his first present; the boy stares at it, his eyes immense with wonder; the father urges him to open it; the boy says simply, "I do aot care what...
Hollywood can proceed to the ultimate in cinematic realism by using a hemispherical screen and central projector (as in a planetarium), by using an annular lens (as sometimes used on submarine periscopes), which presents a doughnut-shaped picture to the eye (or camera) covering 360° around the horizon, and practically to the zenith. This picture, projected back through the same type of lens, would recreate the original scene; the camera could project downward from the center of the theater, and could include two such lenses in a polarized system on a common axis for 3-D; also the vibrating...
Ordinary light vibrates transversely (like shaking a rope) in all directions, but if it is passed through a Polaroid filter, it emerges with nearly all of its waves vibrating in the same direction. The two films exposed by the cameras are thrown on the same screen by two projectors. In front of one projector is a Polaroid filter that passes light with its waves vibrating, for example, vertically. In front of the other is a filter that passes light with horizontal vibrations. The viewers get glasses with lenses of Polaroid plastic. One lens passes light from the screen that...
...original projector were not complicated enough, Chairman Coles and his staff have festooned it with added gadgets manufactured in basement workshops. They can simulate an eclipse of the sun, complete with corona and Baily's beads. They can work up their own thunderstorms: dark clouds move across the dome as lightning flickers and thunder rumbles in the public address system. Added switches on the control panel can send a shower of meteors drifting down the sky. Fireballs flash and explode overhead...
