This spiral tiling with 14-fold symmetry was built from three equilateral polygons, including a heptagon. There are several ways to fill the center so that the tiling is a complete tessellation. A rhombus and the two polygons other than the heptagon can be used, though the complete tiling becomes 7-fold.
Edge-to-edge heptagons can be followed from the center outward. The tiling might extend infinitely(?)

I once made a drawing of the way regular pentagons "spiral" out from a central pentagon, with diamond shapes inbetween. Hand coloured I was pleased with it, though I'm not sure where it is now.
