Granny Dance
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.
