Six Orbs Form a Triangle

Photo date: March 26, 2015. Photographer: Mark Mahin.

The photo below was taken in Grand Central Station in New York.

We see that six of the orbs are arranged in a big triangle, while another purple orb lurks among the commuters. You can actually seem to see a faint face in the purple orb, but since it is kind of a borderline case, I won't show a closeup of it.
