Parallax Angle
The sun reflecting off the windshields of two cars, up through a balcony railing, and through a door, to cast dual shadows onto a ceiling. The cars are parked about four feet apart, by chance, at precisely the correct angles*. One windshield was relatively flat (Sun's reflection behind photographer's left) and the other more curved (Sun's reflection behind photographer's right).
The varied parallax caused by the different angles of sunlight from the two windshields (one of the cars parked at a slightly crooked angle, and the different distances to the railing, doorway and photographer create a surprising image.
*Out of literally thousands of times over several years, this is the only time I have seen double shadows.
