@lastrami_ Thanks Lastrami - I'd love to be able to tell you how these spots came to be but I'm not quite sure LOL. This was a huge, tall, oval-shaped, shiny, holey sculpture and whenever you took a photo of it - either into the holes or from the outside - all sorts of strange reflections etc happened. It was great fun!! :)
Oh, a sculpture! I thought it was something in your household like a skimmer or something like that :D Well, that's the fascinating mystery of abstract shots ;)
