The Geoscope was a proposal by Buckminster Fuller around 1960 to create a 200-foot-diameter (61 m) globe that would be covered in colored lights so that it could function as a large spherical display. It was envisioned that the Geoscope would be connected to computers which would allow it to display both historical and current data, and enable people to visualize large scale patterns around the world. Several projects by his students to build a "miniature Earth", starting with a 20-foot version at Cornell University in 1952, were precursors of the Geoscope proposal. Before proposing the Geoscope, Fuller had invented the Dymaxion map, a novel map projection for the whole Earth.
