Straight-ribbon Woven Dodecahedron
This collection of 20 loops of straight ribbon uses the widest possible ribbon to consistently weave around a dodecahedron symmetrically. -
Truncated 600-Cell
We constructed this design at a recent Stanford University Math Camp. -
Meta Triamond Lattice
A beautiful lattice with some surprising symmetries. -
Understanding Icosahedral Rotations
An explanation of how the rotations of a snub dodecahedron can defy our intuitions -
Hidden-Surface Removal for N-Dimensional Polytopes
Projecting an N-dimensional polytope to 3-d is easier to see when you show only the "front" -
Building the Hyperdo
Step-by-step instructions for building the Hyperdo kit from Zometool -
Oblique Projections of A4 Polytopes
Two different A4 polytopes, relatives of the 5-cell, showing ghost symmetry in their projections to 3D and 2D -
Perfecting Steve Baer's Triple Dome
Steve Baer's triple dome at Drop City can be built precisely with real Zometool struts, as a particular subset of a projected H4 polytope. Three alternatives are discussed. -
