I do not think it is easy to guess what this is, but I will give you a photographic clue. It is shot at 50mm zoom from a distance of about 10-15 meters. It is shot with the shutter at 1/6th of a second and aperture of f/2.8 at ISO 800. Shot in Oslo, thursday night about 7 pm. In other words: a rather large object shot at nightime. The answer will come in three days on a followup picture.
