NYTimes Video Projections on a Globe Make Planetary Data Click
The display is Science on a Sphere (http://sos.noaa.gov/) , a pioneering system for presenting planetary portraits gathered from satellites and other spacecraft.

Though stationary, it gives the illusion of spinning as the images move, and the nearly invisible wire that holds it up makes it seem to be floating in space.
