For the first time since before technology was invented, this sculpture is available. I've always liked it, so I'm happy to see it again!

There are six regular convex polytopes in 4D, which are analogous to the five Platonic solids in 3D. This is the sixth, the hypericosahedron, with 600 tetrahedral cells.

This was the hardest of this group to make a printable model of. For a Schlegel diagram one would need quite a large size to allow the amount of interior complexity required, and it gets difficult to build as well as expensive, so I used this face-first projection suggested by Henry Cohn. Some of the tetrahedral are collapsed and become planar, but on the plus side the complexity is on the outside where you can see it!

Giraffe with partially open body through a Voronoi structure.
The body hosts two balls with a Voronoi structure, one inside the other.

Found on an alien beach. Left by what creature?

A smaller model is here.

This prickly sphere looks amazing in 3D, you can lose your self for hours playing and being mesmerized by it.
It doubles as an acupuncture ball, roll it around on your body ( I love it on my head) to relax and circulate your blood, the skin feels tingly afterwards. 

A third order 3D Hilbert curve with 1mm thickness & clearance. 2/8 blocks are rotated so that it forms a loop instead of an open curve. See http://www.shapeways.com/model/111039/tiny_hilbert_cube_variation__1_5mm.html for a 1.5 mm version and http://www.shapeways.com/model/109525/ for a 4th order version.

This is the first interlocking cube I ever designed. It consists of four pieces which fit together with a series of sliding movements. It is not too difficult for the average puzzler but will provide a satisfying challenge at this small scale. The completed cube is 1.6cm on each side.
