This may be entirely off-topic, but... why use the Star of David as your thumbnail? For a mod all about hexagons, I'd have expected a hexagon in the thumbnail, instead :)
The thumbnail is of the fourth tier of coins. The shape of the first tier is a hexagon. The shape of the second tier is a hexagon with slightly more pointed corners. The shape of the third tier is more like a six-pointed star, and this last tier is a fully formed six-pointed star. The six-pointed star is the result of stretching out the corners from a hexagon. It has nothing to do with Judaism. I guess I'm not cultured enough to have seen that myself.
