Darwin's Cube
 
Catalogue reference: M1094
 
Darwin's Cube is a modular pattern base designed by David Mitchell. Many contrast pattern cubes can be developed from this base by bringing out some or all of the hidden flaps. The modular structure of Darwin's Cube is directly analogous to the modular structure of the Sonobe Cube.

Diagrams can be found in Synergy 2 - Patterning the Modular Cube Part 1 - David Mitchell - Water Trade 2002.

Heinz Strobl's Cube
 
Catalogue reference:
 
Heinz Strobl's Cube is a very strong modular cube made from three long strips arranged in a Borromean relationship. Strobl Cubes can be linked together by threading them onto other strips to form many interesting macro-modular structures.

The Intermediate Cube
 
Catalogue reference: M1093
 
David Mitchell's Intermediate Cube is a very strong design made from six fairly complex four-armed modules (which occur as 'intermediate folds' in the Enigma Base folding sequence) by interweaving the arms to form the top layer of the faces.

Diagrams have not yet been published.
 
The Simplex Cube
 
Catalogue reference: M1091
 
The Simplex Cube is a robust and versatile design by David Mitchell. Like Sonobe modules, Simplex modules can be used to construct any form whose faces are either squares, or silver triangles, or a combination of the two.

The Simplex Cube is made from the twenty-four L-type Simplex edge-pocket modules, each of which creates one square of the 2x2 chequerboard pattern design shown. Diagrams have not yet been published.

The Mondrian Cube
 
Catalogue reference: M1092
 
David Mitchell's Mondrian Cube is an attractive decorative variation of the 12-part Corner-Pocket Sonobe Cube. The relative proportions of the small and large squares within the pattern can easily be varied.

Diagrams can be found in Synergy 3 - Patterning the Modular Cube Part 2 - David Mitchell - Water Trade 2002.
 
The Two Fold Cube
 
Catalogue reference: M1045
 
David Mitchell's Two Fold Cube is a minimalist modular origami design made by combining modules produced from a square using only two folds. Eight modules go together to form an open-ended square-section tube. The final design is formed from three such tubes arranged in a borromean relationship.

Diagrams published in British Origami 186 October 1997.
 
The Hosoya / Tsak-man Cube
 
Catalogue reference: XM1100
 
The Hosoya / Tsak-man Cube is an elegant 2-part design which was originated independently by Haruo Hosoya (in Japan) and Ho Tsak-man (in the USA). It is not known which of the two discovered the design first.

Diagrams for Ho Tsak-man's cube can be found in The Flapping Bird issue 20 1974.

Diagrams for Haruo Hosoya's cube and variations can be found in Kunihiko Kasahara and Toshie Takahama's 'Origami for The Connoisseur' - Japan publications 1987 - ISBN 0-87040-670-1.

The module for the Hosoya / Tsak-man Cube is identical to the module for Robert Neale's Rhombicuboctahedron.
 
The Eureka Cube
 
Catalogue reference: M1051
 
The design of the four modules required for David Mitchell's Eureka Cube depends almost entirely on the division of the diagonal of the square into thirds, a procedure which not only determines the shape and proportions of the modules but which also almost automatically produces the tabs and pockets that hold them together. Eureka, indeed!

Four modules of the same fundamental design, but folded from a 4x4 grid, will go together to form a rather delicate 1x1x2 cuboid. Three reconfigured modules will go together to form a triangular prism with dimpled triangular faces.

Diagrams were published in Synergy 1 and can be viewed on-line on this site.
 
2 into 1
 
Catalogue reference: M1095
 
2 into 1 is a modular assembly puzzle designed by David Mitchell. The four modules (each of which is itself a traditional Japanese single-piece paperfold sometimes known as the traditional coaster) can be assembled in a straightforward way to make two cubes, then taken apart and re-assembled to form just one.

Diagrams can be found in Paperfolding Puzzles - David Mitchell - Water Trade 1998 - ISBN 0-9534774-0-1
 
3-part Cube
 
Catalogue reference: M1103
 
There are many 3-part cubes in the origami literature, but this one by David Mitchell is unusual because of the way the surface of the cube is divided among the modules. While each of the faces visible in the picture is divided into areas of two different colours, each of the hidden faces is homogeneous, with the result that the cube looks entirely different when viewed from the opposite angle.
