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. 2. The method of claim 1 , wherein the portion of the shape-matrix is a shape nugget.3. The method of wherein claim 1 , for each particular arrangement in the set of arrangements claim 1 , the particular shape nugget is a password or identification code.4. The method of claim 1 , wherein the set of blocks is tessellated.5. The method of wherein claim 1 , for each particular block in the set of blocks claim 1 , a corner shape in the particular block includes a surface that is in the interior of the particular block and that is visible from outside the particular block.6. The method of wherein claim 1 , for each particular arrangement in the set of arrangements claim 1 , each corner shape in the particular shape nugget differs in color claim 1 , orientation claim 1 , or geometric shape from at least one other corner shape in the particular shape nugget.7. The method of wherein claim 1 , for each particular arrangement in the set of arrangements claim 1 , the particular shape nugget differs claim 1 , from the shape nuggets in the other arrangements claim 1 , in one or more of the following respects: color of constituent corner shapes claim 1 , geometric shape of constituent corner shapes claim 1 , and orientation of constituent ...
