The Grannies,
(the dancing ones, not the sitting ones), are derived from the geometry
diagramed in pink and green nearby. Each dancing granny is a modification
of the square conjoined with two triangles.,or its mirror image. Tiling
afficionados may recognise the pink and green arrangement as one of Johannes
Kepler's,( he of the Keplerian laws of planetary motion), basic tile types.
The snorkle girls, or divers, are, as I recall,derived from a different
disection of this Keplerian geometry.
