Both Stairways Had Mysterious Orbs

Photo date: January 31, 2017. Photographer: Mark Mahin.

I took the photo below at Grand Central Terminal in New York. In front of each of the stairways we see a mysterious orb.

We see something very bizarre in the lower middle of the photo. The information clerk behind the glass window seems to have a strange "triangle head." It is as if there is some black triangular shadow where his head should be.
