A Bill picture is a sequence of nested regular polygons in which subsequent polygons are each rotated so that they begin one vertex further. The term was coined by Trott
(2004, pp. 88-89) and commemorates Swiss artist Max Bill, who in 1938 created
a picture showing a similar arrangement of the equilateral triangle through octagon
(Huttingerr 1978, Bill 1987).

The figure above shows the Bill picture including regular polygons up through the
regular dodecagon.
