Beaded icosahedrons

Beaded models for icosahedron are harder to make. This is because each vertex has five edges connected to it, so one has to face a pentavalent coordination. It is very difficult, if not impossible, to make a pentavalent coordinate with spherical beads. But if want use beads with long aspect ratio, stable and beautiful icosahedral structures can still be made.
