Inside a ball
On the beach of Giulianova (Teramo, Italy), this structure recalls (one half of) the usual soccer ball. There are 6 blue pentagons and 10 hexagons, red or yellow: exactly half of the 12 pentagons and 20 hexagons in a soccer ball. And it is not a casualty the fact that in the whole structure the pentagons are exactly 12.
