At Grand Central Terminal in New York, I have hundreds of times photographed mysterious orbs aligning with architectural lines in the station (as you can see in this series). Below are 4 photographs from the same day showing such alignments. The first three orbs have their bottom edges aligned with an architectural line, and the last orb has its top aligned with an architectural line.
