Another classic from Koski, an ongoing dissection of an interesting combo: the greens are in the six IVM directions, whereas the reds come from five-fold world. You can see the reds in action, building the rhombic triacontahedron (bottom left). The overall shape (transparent) is all reds and greens.
The colors refer to Zome, the construction kit, and the screenshot above is from vZome or the virtual Zome builder. It's a standalone Java application. Feel free to grab.
One of David's fascinations has been breaking down all these tetravolumes into sums of phi-scaled modules, the S and E modules in particular. You'll find out more about these tetrahedrons in this blog and elsewhere.
