Shape-matrix geometric instruments having numerous applications including, but not limited to, anti-counterfeiting, graphical passwording, games, and geometry education. A shape-matrix geometric instrument is a manufacture and/or a method whose design is based on a shape-matrix that, in turn comprises a set of building blocks that are N-dimensional polytopes. Corner shapes are positioned in or near the interior corner spaces of at least ones of the shape-matrix building blocks. At least ones of the corner shapes differ from others in at least one property or aspect including, for example, geometric shape, orientation within the building block, and one or more surface “finishes,” such as color, shading, cross-hatching or real or apparent texture.

The method of creating a three-dimensional (3D) puzzle of an object includes receiving a 3D model of the object; sequentially extracting a plurality of preliminary segments from the 3D model, and generating a plurality of two-dimensional (2D) printable segments corresponding to the plurality of preliminary segments. The plurality of printable segments may be configured to be printed to create a plurality of printed segments that may be configured to be selectively coupled together to form a 3D representation of the object.

A bottle puzzle used as a training or learning tool for children and adults with cognitive disabilities has puzzle pieces with uniquely shaped concave and convex walls, with only one wall in one puzzle piece matching another wall in a different puzzle piece. Each puzzle piece is a fully contained compartment capable of holding and dispensing beverages. When the puzzle pieces are put together, they form a normal bottle that can be filled with beverages.

The invention generally relates to multi-dimensional puzzles for teaching, entertainment, and construction. One embodiment of the invention comprises two forms, one planar and one non-planar, which comprise a plurality of protrusions and recesses. These forms may be assembled by selectively interconnecting the various protrusions and recesses to create multi-dimensional shapes such as a cube, cylinder, and sphere among many other possibilities.

The Alphacube invention is a collection of modular shapes that form cubes, each letter of the alphabet and that are a twisty cube puzzle that can be solved for each letter of the alphabet. The pieces can both build structures and communicate verbal messages. They are a toy, puzzle, and an educational tool to teach literacy in a fun and engaging way. The pieces can also be assembled into artistic shapes or into basic shapes that describe animals and simple things like a small hole on a flat surface.

The invention relates to a construction unit configured to interlock with other construction units to create a variety of different shapes.
