PolyRing

Pattern inspired by a hexagonal floor tile Nicole Platz found. http://howtomath2014.weebly.com/blog/patterns I didn't work out how to construct the rings directly, but did different components. It would be simple for n=6 (like the floor) or n=3 or 4, but really tricky for weird n. So... first draft!
