David Mitchell's Origami Heaven - Modular Origami - Irregular Assembly Designs
 
Irregular Assembly Designs
 
A selection of designs made from identical modules but assembled in an irregular way.
 
  David Mitchell's Butterfly Tetracube is a delicate design made from four identical modules. The modules are first combined in pairs then woven together to create the form. There are two ways to connect a pair of modules. The weave will only work if the two pairs of modules are connected in different ways.
