Adam Savage's One Day Builds: Hyperdodecahedron Model Kit!

A perfect weekend project is this beautiful model kit: the Hyperdo from Zometools. Adam received one based on the recommendation of his good friend Kevin Kelly, and spends the day putting this complex geometric object together. It's a hyperdodecahedron--or more specifically the 3D projection of the 4D object known as the 120-cell. It's not a simple assembly, but the finished model is so very rewarding!

      @Luke Hawkinson that is very true, but I bet Adam could manage to pull it off; even if it took some help.

      @Adam Savages's Tested, Have you considered how you are going to mount it? Could you make a gyro mount for it? and would that actually work to show of the symmetries inside it with little to no external power. solar panels running slow gears maybe? something like a half turn every 3 hours on all 3 axis. heck one could even put a sperical led in the middle of it turning it into a dyson sphere.

      @Jason Krise the level of complexity involved in that would be several orders of magnitude past the infinity mirror dodecahedron he built awhile back. the only way i can think to do that would be to make ARGB light modules that are inside the nodes. wiring the thing would be a separate challenge.

I even show a very simple and easy way to weave synergetic spacetime that is both low cost and low tech. there's a lot of useful applications for these principles and patterns and I can't wait to see more people engage and create a world more in line with the way Universe is doing it.

    It's the 4D equivalent to the dodecahedron. The 'hyper' equivalent to a flat polyhedral face is called a 4D 'cell'. The full object is exactly 120 dodecahedral cells all perfectly touching each other with 3 around every edge. All the cells here (aside from the central one) are squished by their projection into 3-space. That's also why many of the cells seem to have disappeared when more than one projects to exactly the same location. Even so, I think a few layers of cells were left out because they'd be unworkably flat. Just know that in the true 4D space they are all perfect dodecahedrons with no room to add any more.

    The second step is 12 dodecahedrons wrapped around a central dodecahedron, which was step one. Since they dont tile evenly in 3d, they had to be deformed to make them fit. Steps three and and four connects the outermost surfaces to form an outer geodesic sphere.

    The 120-cell is my favorite shape. I'm actually working on a little C++ library that explores the dodecahedron (using the A5 group), and I'm thinking of generalizing it for more shapes in different numbers of dimensions. EDIT: ah, only 45 cells. oh well, still neat. Also, it seems it needs mentioning that the “hyperdodecahedron” (the 120-cell) is a 4-dimensional regular polytope (a 4-dimensional “platonic hypersolid”, of sorts).
