Geodesic is a design by R. Buckminster and looks like a "Hostess Sno-Ball". Built by triangles snap together into tetreahedrons.

The geodesic dome was invented in the late 1940's

The 'big ball' at Epcot in Orlando Florida, is a Geodesic sphere. The old dome-like playground equipment is based on the same structure as a geodesic dome. I've posted a couple of links about geodesic domes with some pictures.

Urban Airship was created in 2009.
