Tiling the plane with regular polygons is a fascinating subject, both mathematically and graphically [1,2,3], with a long history . It is now exactly 400 years since the mathematics of tilings were first discussed in Kepler's book Harmonices Mundi of 1619.
A tiling of the plane by polygons is a subdivision of the plane into bounded polygonal regions that either are disjoint, share a vertex, or share an edge. Restricting the faces of the tiling to be regular polygons brings lots of rigidity while still allowing much interesting variety. Standard results on the subject can be found in Wikipedia.
The application implements the method described in [a] and [b] to acquire, represent, and compute periodic tilings of the plane by regular polygons. The proposed approach is reminiscent of the regular systems of points discussed in the classic book Geometry and the Imagination . The user can choose one of the tilings from two acquired sets, named acording to the sources  and , setup the parameters, and save the image. The proccess of acquisition is described in [b].
