Weird Image in the "Flag-Sitting" Orb?

Photo date: November 14, 2016. Photographer: Mark Mahin.

I took the photo below in Grand Central Terminal in New York. We see a strange orb seemingly perched on top of the US flag in the station.

A closeup of the orb shows something very strange. In the orb's center we see a triangle shape, and something to the right of the triangle. It looks rather like an image of a mouse eating a triangular block of cheese. But there isn't enough detail for me to claim we are clearly seeing a depiction of something.
