Margazhi - Day 10

Right middle - A hexagon is chosen. Right top - One of the sides (bottom) is removed from the hexagon. Right bottom - The incomplete hexagon is rotated by 150 deg and joined to the earlier one. After twelve such rotations (12 x 150 = 1800 = 5 x 360) we come back to the original. This, after colouring, is shown.
