It rains a lot here, it's raining right now. I have no sound deadening, you'll see when you see the final pics. I'm undecided on the trunk right now.

It's stronger than a T. I'm not a structural engineer so can't offer any better explanation. Perhaps twohoos or mikegarrison will chime in.

Why did they do this strange triangle design in the upper windshield corners?!
Therefore the triangle at the front makes sure that the part of that bar that connects to the top of the cage connects at a node instead of just in the middle of the bar. With out the node, any force directed along the first bar would create a bending moment in the top bar. With the node, the bending moment is countered when you put the bar from the triangle into tension.

To me, cthree's cage looks like an extension of a geodesic dome, modified to fit into a non-spherical space.
- Wikipedia
A geodesic dome is an almost spherical structure based on a network of struts arranged on great circles (geodesics) lying approximately on the surface of a sphere. The geodesics intersect to form triangular elements that have local triangular rigidity and yet also distribute the stress across the entire structure. It is the only man-made structure that gets proportionally stronger as it increases in size. When completed to form a full sphere, it is known as a geodesic sphere. Of all known structures made from linear elements, a geodesic dome has the highest ratio of enclosed volume to weight. Geodesic domes are far stronger as complete units than the individual struts would suggest. It is common for a new dome to reach a "critical mass" during construction, shift slightly, and lift any attached scaffolding from the ground.
