This morning I was a passenger in our car and had the opportunity to take this picture of one point in the sky where there were waves moving in three different directions. You can see the waves in this picture, but with a wider view of the sky via my eye, it was pretty spectacular. I've never seen anything like this.
The wave directions were: N-S, E-W, and NW-SE
