Bead model of small stellated dodecahedron

Another class of bead models made by Mr. Horibe is the small stellated dodecahedron, which is one of the Kepler–Poinsot polyhedra.



The basic idea of making this kind of dendritic dodecahedra is to choose a suitable size of Goldberg polyhedron and then grow a short segment of endcapped carbon nanotube along each pentagon. In this particular case, the endcapped CNTs are just hemisphere of C20s. Similar trick to make dendrite-like structures is used in many of Mr. Horibe's work.
