→Plane Tessellations
Other tessellations of the plane exist. See for example the tilings of [[M.C. Escher]], such as the one which is illustrated here. Such tilings are not tessellations, in that they are not comprised of polygons. However, these tilings are based on one of the above named types of tessellation.

The tiling illustrated is based on a regular tessellation of squares.

A tiling is periodic if, when translated in at least two non-parallel directions the tiling 'merges' with itself. A collection of tiles is aperiodic if the collection tiles the plane, but never in a periodic fashion. [[Roger Penrose]] discovered several such tilings in the 1970's.
