Abstract
A plurality of mathematically interrelated modular structures are disclosed which are based on a series of minimal surfaces bounded by skewed polygons. Some six basic modules are described which are capable of being interconnected in various combinations to form finite volume enclosing structures. Appropriately scaled, the modules could be used as structure toys, to create playground equipment or, for the construction of habitible structures. Utilizing these structural modules, it is possible to construct large assemblies having parallel planar structures within the enclosed space which could be considered floors and ceilings of multilevel structures.
