Anyway, I would have to personally say dust stirred up by some cleaning or renovation. I see stuff all over the place there. And since we know it was taken with a flash (EXIF data, flash fired, auto) and it was wide angle (6.7mm) that would explain the wide area of coverage.
No "Orbilitious" seal here from me.
Although, I will say that the square orbs are unique.
