Modulars in Motion
 
  Name: 2-part Decoration

Modules / Paper shape / Folding geometry: 2 modules from squares using standard folding geometry.

Designer / Date: David Mitchell, 1989. Has also been independently discovered by Tung Ken Lam who realised it will squash flat in two directions, thus turning a rather ordinary paperfold into a charming toy. On seeing this I realised that the Skillman Ball will also squash flat, something I had previously not been aware of.

Diagrams: Not yet available.

 
  Name: The Modular Flip Flop is my reconstruction of a design by the Danish paperfolder Thoki Yenn which has become lost (probably because Thoki abandoned it in favour of his one piece version of the same design). The design is a version of a well known mathematical toy with the strange property that it will squash flat in two different directions.

Modules / Paper shape / Folding geometry: 2 modules folded from double bronze rectangles using 60/30 degree folding geometry.

Designer / Date: David Mitchell, 1989.

Diagrams: Not yet available.

 
  Name: Snap Hexahedra - made from Sonobe, Corner-pocket Sonobe, Sonobe triangle or Letterbox modules can be collapsed flat then popped back into shape.

Modules / Paper shape / Folding geometry:

Designer / Date: Larry Hart published a single-sheet design for a snap hexahedron in the late 1980s. It seems obvious that the same principle could be applied to a modular hexahedron but I am not aware of knowing about this before I came across the idea while playing with snap silveroctahedra in 2015.

Diagrams: Not yet available.

 
  Name: Silveroctahedra and Pop-up Silveroctahedra

Modules / Paper shape / Folding geometry: 2 sets of 2 mirror-image modules from squares using standard folding geometry. Can be made from many different parallelogram and triangle modules.

Designer / Date: David Mitchell, 1989 and 2016.

Diagrams: On-line diagrams are available on the Devious Devices page of this site.

 
  Name: Twin Deltahedral Dodecahedra - convertible design.

Modules / Paper shape / Folding geometry: 6 modules from silver rectangles.

Designer / Date: David Mitchell, 2017.

Diagrams: Not yet available.

 
  Name: (Modular) 2-Way Tube - a modular version of Robert Neale's 2-Way Tube (which can be made (in several ways) from a single sheet of paper or light card).

Modules / Paper shape / Folding geometry: 2 modules from any rectangle using standard folding geometry.

Designer / Date: David Mitchell, 1997.

Diagrams: On-line diagrams are available on the Devious Devices page of this site.

 
  Name: Colour-Change Collapsible Cube - begins as a square section tube which can be twisted and collapsed to create an odd-looking cube. The cube will squash flat sideways and can be manipulated in the palm of the hand to cycle through all four coloured faces in turn.

Modules / Paper shape / Folding geometry: 4 modules from silver rectangles.

Designer / Date: David Mitchell, 1993.

Diagrams: On-line diagrams are available on the Modular Designs page of this site.

 
  Name: Rotating Ring of 8 Rhombic Tetrahedra

Modules / Paper shape / Folding geometry: 4 modules from silver rectangles.

Designer / Date: David Mitchell, 1995.

Diagrams: In Mathematical Origami - David Mitchell - Tarquin 1997 - ISBN 189961818X.

 
  Name: Rotating Ring of Six Tetrahedra

Modules / Paper shape / Folding geometry: 6 modules from 2x1 rectangles using root 5 folding geometry.

Designer / Date:

Diagrams: Not yet available.

 
  Name: Elite Flexicube

Modules / Paper shape / Folding geometry: 24 modules from silver rectangles.

Designer / Date: David Mitchell, 1992.

Diagrams: Not yet available.

 
  Name: Ad Infinitum - an endlessly revolving toy

Modules / Paper shape / Folding geometry: 4 modules from squares using standard folding geometry.

Designer / Date: David Mitchell, 1995.

Diagrams: On-line diagrams are available on the Modular Designs page of this site.

 
  Name: Back to Front - a simple action toy in which rotating the elements in relation to each other brings each to the front in turn.

Modules / Paper shape / Folding geometry: 3 modules from squares using standard folding geometry.

Designer / Date: David Mitchell, 2004.

Diagrams: Not yet available.

 
  Name: Squashy Star is a star that is capable of being squashed flat in all three directions.

Modules / Paper shape / Folding geometry: modules fron squares using standard folding geometry.

Designer / Date: David Mitchell, 2011.

Diagrams: Not yet available.

 
  Name: The Tube Cube is an odd cube made from six linked tubes which will squash flat.

Modules / Paper shape / Folding geometry: 6 modules from squares using standard folding geometry.

Designer / Date: David Mitchell, 2014.

Diagrams: Not yet available.

 
  Name: Mothership - design made using Paulo Mulatinho's UFO as a macro-module - from squares.

Modules / Paper shape / Folding geometry: Each UFO is made from 2 modules from squares using standard folding geometry.

Designer / Date: David Mitchell, 2001.
