The Geoscope was a proposal by Buckminster Fuller in 1962 to create a globe, which 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 globe.
Many of Fuller's ideas for the functions of the Geoscope are now being realized by virtual globes.
Fuller did not limit his use of the term "Geoscope" to the diameter globe proposed for installation near the U.N. He also used it to refer to smaller globes to be viewed from the inside outwards toward the stars.
Paraphrased from Critical Path:
The Geoscope is a monumental display of rocks at the La Lozère motorway service at junction 32 of the A75 autoroute at Albaret-Sainte-Marie in the department of Lozère, France. It is sometimes described as a geological museum. 45 stones, each weighing many tonnes and accompanied by an interpretive panel are artistically arranged in a circle in an old quarry.
