Our latest dome, a dodecahedron with an internal icosahedron. This one was a lot of work for a few reasons. First, Morgan had to do lots of the math out on paper because a calculator doesn't exist on the Internet to indicate the measurements of the orange struts. Second, while it was easy to drill holes in the struts using the family Dremel drill, we used tiny zap straps as connectors. If you screw up with a zap strap, you have to cut it and start over. What a process. In the end, totally worth it.
