Abstract: The present invention is comprised of a set of interlocking pieces whereby the base set of four different pieces provide extensive opportunity to assemble patterns two dimensionally and build three dimensionally. The unique asymmetrical mortise and tenon system allows for continual expansion of engaged forms by joining the pieces. The edge profile establishes a design criteria for developing different shaped pieces in addition to the four base pieces. The modular system of interlocking pieces takes advantage of the structural and spacial characteristics of reinforced concrete that other building configurations do not. This invention has the potential to be used for full scale construction as well as for an educational building toy.

Abstract: A multi-set assembly puzzle (100) whose flat pieces correspond to the panels of a soccer ball. A 32 piece complement comprises 20 hexagons (102) and 12 pentagons (104). Grooves (112) in all polygon sides (110) must have a cylinder (114) attached in it's right (R) else left (L) portions. Sides (110) adjoin only RR else LL. Adjoining pieces may be coupled by inserting a single connecting pin (120) through their aligned cylinder's centers (118). The Rs and Ls of the polygons' sides (110) may be configured to produce 22 different subspecies. The sides (110) are grouped in 90 adjoining pairs which are randomly assigned R else L. The polygon subspecies are then found by examining the Rs and Ls of their sides, and their quantities become the specification for the complement. Successive specifications are compared to all previous specifications. Identical specifications are eliminated, but the former set has another solution, and is rated less difficult.
