I love the how the butterflies or pointed towards the other faces
Yes, The basic idea was, that the same color butterflies go in the same direction.
And this way, if you put down the puzzle, every time you will see the same color butterflies on the Left corner go around the puzzle.
And the other thing:
The spots on each butterfly are the same as the neighbor butterflies colors. So with this, the are no identical butterflies at all on the puzzle!
