They were first designed by Buckminster Fuller, who happened to be my father's professor at Southern Illinois University at the time, so it must have been in the early 1960's. Since my father had a background as a carpenter, Bucky actually assigned him to supervise building the first one. It didn't stand up, though--something about the students who were building it having too much beer! It’s a geodesic dome.

Each of those 960 flat panels is sub-divided into four triangles, each of which is divided into three isosceles triangles to form each point. In theory, there are 11,520 total isosceles triangles forming 3840 points. In reality, some of those triangles are partially or fully nonexistent due to supports and doors; there are actually only 11,324 of them[4], with 954 partial or full flat panels."
