So whats really going on here then?
Looks kind of like a slightly turbulent, highly-magnified point light source (maybe a specular reflection waaay out of focus?). Is that a thin diffraction ring I see around the top? Doesn’t look like a clear Airy disk, but it looks turbulent.
I feel it should be part of an “Are you a robot?” question.
My guess: some kind of cloth over a hole in a wall, with the light source behind the wall.
My intestines after that really hot Thai curry.
