R. Buckminster "Bucky" Fuller graces the RSVP return envelope. Neat image, eh! Nice and nerdy. It was Jordan's selection. What, did you think that the stamp was just some random choice? Nope.

Bucky was an American visionary, designer, architect, and inventor. He was also a professor at Southern Illinois University and a prolific writer. Fuller was most famous for the invention of the geodesic dome, which is the lightest, strongest, and most cost-effective structure ever devised.

The geodesic dome is able to cover more space without internal supports than any other enclosure. It becomes proportionally lighter and stronger the larger it is. The geodesic dome is a breakthrough in shelter, not only in cost-effectiveness, but in ease of construction.

Their construction is based on extending some basic principles to build simple tensegrity structures (tetrahedron, octahedron, and the closest packing of spheres). Built in this way they are extremely lightweight and stable. The patent for geodesic domes was awarded in 1954, part of Fuller's decades-long efforts to explore nature's constructing principles to find design solutions.
