5-stars were commonly used on the ceilings of tombs and other buildings in Ancient Egypt to depict the heavens. They are usually not connected to one another, but they are connected in this ceiling in the Ptolemaic Denderah Temple to form a sort of tessellation of hexagons and quadrilaterals.

Polyaboloes, polygons formed by joining isosceles right triangles in edge-to-edge fashion, can also be arranged iteratively to form fractal self-replicating tiles. A particular tetrabolo was used to form these two reptiles, with mirroring between successive iterations employed in the right one.

A 3-rhomb iterates to the same fractal as the envelope of the terdragon curve. Mirroring between successive iterations yields a very different looking reptile (right).
