Orbs Love to Align Exactly

Photo date: May 9, 2016. Photographer: Mark Mahin.

The photos below were taken in Grand Central Terminal in New York. We see two blue orbs, each of which has exactly aligned on an architectural line in the station.My photos show this often, much more often than I would expect to see by chance (see here for 85 examples).

Here's another example from the same day. We see a purple orb that has aligned to a wall edge.

Postscript: Here is another example of an aligned orb, from the same day.
