Abstract
Families of rhombus-based two-zoomorph variably assemblable tile sets wherein a single amphographic line delineates different parts of one zoomorph and different parts of a second and different zoomorph as well, and may similarly delineate further fatter or skinnier zoomorphs. All or some of these may, in conjunction with one another, tile the plane in an infinite number of different and interesting ways. These tiles and tilings and patches of tiles may be used in puzzles, in games, for teaching certain aspects of geometry, or for the decoration of fabrics or other surfaces.
Claims6
Families of zoomorphic tiles for tiling the plane, comprising:
- at least one set of zoomorphic tiles, said at least one set comprised of two members, said two members having mutually distinct zoomorphic outlines, said mutually distinct zoomorphic outlines having vertices which map onto the respective vertices of a pair of mutually congruent ancestral rhombuses, said pair of mutually congruent ancestral rhombuses being selected from a subset of rhombs that include two squares and two 60.degree./120.degree. rhombuses;
- a first one of said two members corresponding to a first one of said mutually congruent ancestral rhombuses, said first member including a first side comprised of an amphographic line;
- said first member including a second side adjacent to said first side, said second side comprising a rotation of said amphographic line about one end of said amphographic line;
- said first member including third and fourth sides comprised of a reflection of said first and second sides as an assembly, thereby defining a first zoomorphic outline;
- a second one of said two members corresponding to a second one of said mutually congruent ancestral rhombuses, said second member including a first side comprised of said amphographic line;
- said second member including a second side adjacent to said first side, said second side comprising a rotation of said amphographic line about the other end of said amphographic line;
- said second member including third and fourth sides comprised of a reflection of said first and second sides as an assembly, thereby defining a second zoomorphic outline;
- a plurality of first and second members being capable of assembly into tilings displaying an infinite range of periodicities and into tilings displaying no periodicity.
