Try to create your favorite pattern in 3D space for the 600 cell, the 16 cell or the 5-cell, and fold it in 4D with the slider. The program will only show the orthogonal projection (shadow) in 3D space.

Topographical topology at the Arches National Park in Utah!

Is there anywhere in the world where either the Earth, or its complement, is not a handlebody?

Sensual Mathematics

Some of +Henry Segerman's and my 3D prints were recently used in a student art exhibit at Aalto University, Finland after Henry gave a talk there.

The piece, titled Shadow Lanterns, uses a sequence of {4,3,r} honeycombs for r = 3 to r = 7. The last two are truncations. The artists printed half-models and put a light source at the center, projecting shadows onto cylinders.

There are a number of cool looking projects in this video of the exhibit, and Shadow Lanterns makes its appearance around the 2-minute mark.

I played with the Vive version of this (it's also available on iOS) when I visited Marc. As far as I know, I am the first person in history to juggle three hyperspheres!
