The Stewart Toroids are a good place to start. Select "Stewart Toroids" from the category drop-down list in the toolbar (initially showing "Platonic"). Then just step through them with the Right arrow key. OK, so they start off not too exciting, but keep going. For ones with lots of holes, try:starbase1 wrote:Given the many, many polyhedra available, can anyone recommend an interesting one with lots of hollow spaces? (And tell me where to locate it in the menus!)

Octagon-Drilled Truncated Cuboctahedron

Drilled Truncated Dodecahedron

Rotunda-Drilled Truncated Icosidodecahedron

Cupola-Drilled Truncated Icosidodecahedron

(Select those from the model drop-down next to the category drop-down).

For even more (and some more complex ones), select "Stella Library" from the category list, then "<More Stewart Toroids>" from the model list, and step through them again with the Right arrow.
