Geomags/Supermags: Polyhedra & Fabulous Structures

Discuss types of magnet building toys, and what you can do with them. Pix encouraged! Math welcomed.

This is a little community to talk about constructions made using Geomags or Supermags (or Magz or Magnetix or other similar magnetic construction toys). Posting pictures is encouraged! Links to cool sites is also encouraged.

You can also talk about and post pix of polyhedra or other mathematical structures made using other construction toys (such as Zome), if you like.

Please also feel free to write more abstract stuff about polyhedra in any form (from polygons to polytopes), or provide cool links to things about these topics. Especially with diagrams, if you can! Can be really mathy and technical, or not, as you like.

Below are some reference links.

For any convex polyhedron,
the Euler formula holds:
V - E + F = 2

where:
V is the number of vertices,
E is the number of edges,
F is the number of faces.
