Ekinoid: Copper Model
This was the first model to be built, around January 2009. We wanted to have a look at the structural integrity of the model and also (mainly out of simple curiosity) see how a weathered, copper tiled, surface would look. Note the three outside columns are taking all the load on this model; the central column does not descend to the ground as in the other models. Also note that the three outside columns are actually outside the great circle of the main floor, not supporting it directly; which greatly increases the forces at the respective joints (which is why we modified it in the later designs).
