I also made a paper model. Below, right, is the propello-icosahedron in a five-color pattern. Below, left is its dual, the propello-dodecahedron, in a six-color pattern. (I since gave both of these paper models to John Conway.)
I then cut the slits in the actual CDs (in my studio in New York) and shipped them to Berkeley all in a box, actually smaller than a one foot cube. At Berkeley, in a room adjacent to the atrium, I started gluing them together into sub-assemblies:
The sub-assemblies were joined into triangles which can be seen stacked in piles on the tables in the image below. Then I assembled the oak hub, fiberglass rods, stainless steel wires, and hooks which form the support structure:
The remainder of the construction had to be done in place. The next morning, I brought the components up twenty-something feet in a lift, to assemble and glue them together:
I started at the top and worked my way down to the bottom:
The total construction time on-site was about eight hours. For
pictures of the final result, see my Rainbow
Bits page. For other pictures of the assembly, see Prof.
Carlo Sequin's U.C. Berkeley web page for this sculpture.
