Can you recognize it?

I noticed it earlier today, and loved the nice pattern showing when light is coming through it. For this photo, I set my LED flashlight behind and a thin, white, paper napkin in between to blur those small LEDs. Because it was so thin, I had to tape it to some sturdy objects so it wouldn't shake and mess up my picture. My good, old, 100mm macro lens, allowed me to come close enough to allow cropping to only few millimeters across this picture.
