Notice how the dodecahedron's vertices sit above the icosahedron's faces, and vice versa? Also the edges of the two polyhedra bisect each other at right-angles. The icosahedron has quite a few stellations. Here is one example. Here's another stellation. And another stellation, the ...

What is an Icosahedron? "In geometry, an icosahedron is a regular polyhedron with 20 identical equilateral triangular faces, 30 edges and 12 vertices. It is one of the five Platonic solids." - Wikipedia http://upload.wikimedia.org/wikipedia/commons/e/e2/Icosahedron.gif http://en.wikipedia.o...

An icosahedron is a regular polyhedron with 12 vertices and 20 triangular faces. An icosahedral shell has one of the largest volumes for its surface area, and is thus most desirable for structures made of large numbers of identical components, e.g. Fuller's geodesic domes. A modified form, ...
The disc can be used in another way (FIGS. 5 and 6). If 20 of the struts are arranged on a flat surface in such a way that they form 9 continuous alternated equilateral triangles 17 plus one incomplete triangle 18, it will be seen that ten vertices 19 will be formed by the various...

Three planes contains the 20 vertices of an icosahedron. Their edges form Borromean rings. You can made the Borromean rings using three balloons. This constrution is inspired in a video about the logo of the International Mathematical Union (IMU) designed by John Sullivan (The Borromean Rings:...
