The Moiré pattern could also be caused by the safety material in the glass.  
It's a tinted, safety glass door.  It uses a sandwiched elastomeric material, 
possibly Butacite®, between two pieces of glass, much like a car windshield.

Ann,
Moire pattern from the screen to be sure.

I think that is true but I won't rule out artwork until I go over there and see 
it. A screen door is unlikely to exist in my neighborhood.
