Our Web Hosting Provider

• Our web host is 1&1 (since December 2003).
  They're inexpensive, with excellent reliability and very generous features.
  If you click this link and order from them, I get a "reward" credit.

The background of this page is an anaglyph that I drew using Java. View it with red-blue 3D glasses. It shows 2 layers of a honeycomb (a solid tesselation) composed of cuboctahedra and octahedra. This is a "semi-regular" honeycomb (see H.S.M. Coxeter "Regular Polytopes", section 4.7 (Coxeter01)). For other honeycomb backgrounds, see my Rhombic Dodecahedron Page and this other page.
