That’s what you get when you start fooling around in the office, looking interesting things. It totally pays off to try to look at your own environment with a fresh eye!
I took two variations of the same view. One was with a much wider aperture, focusing only on a fraction of this… thing, but I decided for this one, taken through a smaller “hole”. I kinda like how almost the whole circle in the middle is in focus, not just a curve of it. (Though it could still pass as a landing sign for aliens… 🙂 )
