Pryaminx Gale Warning

In coastal areas you'll sometimes see a Gale Warning signal, a pair of triangular red pennants flying one above the other as illustrated at right.

This pattern simulates the gale warning three times on each side in three different colors. It's an imperfect imitation, but the pattern itself is interesting because it pairs a mobile edge piece with a non-mobile tip piece without tying them to the immobile center piece between them. (Like the tips, the center pieces can only rotate around the corner they're connected to.)
