Projecting Data on a Sphere

necro81 writes "The NYTimes has an article in today's Science section that describes a four-projector system that displays images on a spherical screen. The Science on a Sphere system, developed at the Goddard Space Flight Center and used in some planetariums, can display and animate vast amounts of visual data from the Earth, Moon, Sun, and the other planets. The sphere is suspended by thin wires, and animating the image data gives the illusion of a free-floating, rotating world."
