Modular Origami — Miscellaneous

Tux the penguin

Made from Sonobe module (36 modules). Body and head are separate pieces (30 and 6 modules, correspondingly).
Tux the penguin is a mascot of the Linux operating system. The logo was created by Larry Ewing (lewing <at sign> isc <dot> tamu <dot> edu).

Christmas ornament / pendant

Made from Michał Kosmulski's TEM (Trapezoid Egde Module) (3 modules). Any number of modules from 2 upwards can be used to create similar models. The only limitation is paper's thickness.

Ring - can be worn as a headband

Made from Michał Kosmulski's Sturdy Edge Module (StEM) (12 modules).

Any even number of modules can be connected this way, though the link isn't very strong.

Möbius Strip

Made from Nick Robinson's trimodule (21 modules).
This is one of the rather few modular origami models which are made from an odd number of modules.

Möbius Strip

Made from Nick Robinson's trimodule (23 modules).
This model of the Moebius strip also requires an odd number of modules.

Möbius Strip

Made from Michał Kosmulski's BBU (Building Block Unit) (48 modules: 32 × A2, 16 × A1, hook connection method).

Pentagonal snowflake

Made from Robert Neale's penultimate module (55 modules).

Nuclear mushroom cloud

Made from Thomas Hull's PHiZZ unit (60 modules).

2×2×1 box

Made from Michał Kosmulski's BBU (Building Block Unit) (61 modules: 32 × A2, 26 × A1, 2 × A5 variant, 1 × D19, hook connection method).

14-spoked wheel (tetradecagonal prism)

Made from Michał Kosmulski's Sturdy Edge Module (StEM) (70 modules: 28 from 1:2√2 paper and 42 from 1:√2 paper).
This construction isn’t mathematically exact but is close enough for practical purposes.

Abstract composition “T”

Made from Michał Kosmulski's BBU (Building Block Unit) (75 modules: 36 × A1, 30 × A2, 6 × D1, 3 × E4).

Expanded hexagonal (dodecagonal) prism

Made from Michał Kosmulski's BBU (Building Block Unit) (84 modules: 42 × A2, 36 × A1, 6 × A4).

Cigar / carbon nanotube

Made from Thomas Hull's PHiZZ unit (195 modules).

Steinhaus puzzle

Made from Robert Neale's penultimate module (3*44+3*36=240 modules).
This puzzle, described in Hugo Steinhaus' book Kalejdoskop matematyczny (Mathematical kaleidoscope) consists of six pieces, which can be assembled together to form a cube (as in the first image) or a variety of different shapes (such as the one shown in the second image). All separate pieces are shown in the last image. A similar puzzle, better known in the English-speaking world, is the Soma cube.

Hamiltonian cycle of the cube

Made from Michał Kosmulski's BBU (Building Block Unit) (240 modules: 144 × A1, 96 × E1 variant).

Crystal structure of gibbsite

This origami represents the crystal structure of gibbsite (α-alumina) in the octahedral model and is reproduced on the cover of the book ”Surface charging and points of zero charge” by my father, Marek Kosmulski. Larger image also available here.

Made from Nick Robinson's trimodule (68×4 = 272 modules).

Torus

Made from Thomas Hull's PHiZZ unit (360 modules).

Klein bottle

Made from Thomas Hull's PHiZZ unit (500 modules).
This model was quite difficult to design, as the two sides of surfaces made with PHiZZ modules differ a lot (due to the presence of "bumps" where units join) and the Klein bottle is a one-sided surface. Thus, there must be a place where units pointing out in one direction join those pointing in the other direction. I tested several different solutions before choosing the simplest and most elegant one. Last image shows a close-up of the bottle's mouth, where units with two different orientations are connected. One of the earlier attempts resulted in creating the atomic mushroom cloud model (below). The last picture in top row shows a partially assembled Klein bottle, with inner parts of the "neck" visible.

Regular bottle

Made from Thomas Hull's PHiZZ unit (336 modules).
This was made from the Klein bottle by detaching the elongated neck.
