Instructions

Directions for making polyhedrons with the penultimate module
Directions for making the compound of 5 tetrahedrons (pictured above)
Directions for making greater/lesser stellated dodecahedrons with Jeannine Mosely's module
Sketchy directions for making the compound of 12 dodecahdrons. (This assumes you're familiar with the penultimate module above).

Pictures -- ``Penultimate Module''

Compound of 5 tetrahedrons --- Another one. --- And a third.
I've only made three, because these take a lot of work....
Gallery of 5-Tetrahedron Models Made by others
These are beautiful -- keep sending me pictures -- I'm happy to add to the gallery!

Compound of 5 octrahedrons.

Compound of three rectangular prisms.

Stella Octangula.

Lesser Stellated Dodecahedron.

One of the stellations of the icosahedron

Snub Cube --- Dual of the Snub Cube --- Obscured picture of the snub dodecahedron

Icosidodecahedron and Dual (Rhombic Triacontahedron) --- Side View, Top View --- Another One.

Another Rhombic Triacontahedron.

Polar Zonahedron: n = 5 --- Front View , Side View. (Ray-traced polar zonahedrons)

Many dodecahedrons.

Rhombiicosidodecahedron

Rhombitruncated cuboctahedron.

Rhombicuboctahedron. (plus another by A. Gaedicke of Chile).

Truncated icosahedron. --- Another one --- One made by Shannon Nichols

You tell me (I don't know the name for this), Although I think it's a compound of 12 dodecahedrons

Pictures -- Other Modules

Rhombicuboctahedron (with pointy-things), A different one -- The outer modules are from Yamaguchi's book Kusudama: Ball Origami (Japan Publications, 1990). The inner modules are kind of like the Sonobe module (see below). If enough people pester me, I'll diagram it.
Greater Stellated Dodecahedron -- Jeannine Mosely's module (see above for directions).
Sonobe Rhombicuboctahedron and Dodecahedron. The Sonobe module is diagrammed in Origami for the Connoisseur, by Kasahara and Takahama (Japan Publicaions, 1987), and is very flexible.
Sonobe Icosahedron.
Little Turtle Dodecahedrons. The Little Turtle module is diagrammed in Fuse's Unit Origami (Japan Publications, 1990). It is also very flexible, but I would highly recommend gluing these if you want them to last -- they are serious explode-on-impact modules. However, I think they are also beautiful.
Little Turtle Icosidodecahedron.
Random stuff on the piano of origami.

I make no recommendations about these -- various people send them to me and I link them in. I hope that they are helpful, and I appreciate people spending the time to make them.
