All of us nerdy homeowners are looking for ceramic, marble, granite, quartzite, glass, or similar. We need a few sizes. Our square tiles are 18x18 inches (3/8 thick, 3/8 grout lines) in larger rooms and about 2x2 or 3x3 inches (1/8 thick, 1/8 grout lines) in showers. Tiles of generally similar area would be good. We also need wall tiles for kitchens (behind the sink) and for bathroom walls.

The rhombic Penrose tiling is basic and nice. The Voronoi transform of it is better I think, being less likely to chip or injure feet because there are no acute angles.
