Torrey Smith and friends have put in a lot of effort for their preparations towards Burning Man 2013. The goal was to make a geodesic dome for the Sextant Camp at Burning Man 2013 using Domerama’s  3V 5/9 Kruschke calculator (resulting in a 3V flat at the base) with the following input:

D Strut: 5.859′ (That corresponds to a total strut length of exactly 6′, which is easy to transport and withstood Torrey’s bending test for “climb-ability”).  That results in a diameter of 26.6′, a height of 15.8′, and a floor area of 519 square feet.

And the real surprise is how the geodesic dome struts themselves were made: with waterjet cutting gear which consists in using a mixture under high pressure containing water and abrasives pushed through a tiny nozzle, creating a jet spray able to cut through metal. See the images below and the many videos describing the process.
