It's a mirror on hinges - see the next shot I posted - and the best bit is you get to swivel it to whichever angle you choose. It's in a fantastic park full of sculptures, which is where I took all my shots for this challenge.
I like the way the subtle effect sneaks up on you... You don't get to notice much from the thumbnail and even when you open it's not immediately in your face. Is it a mirror in a garden or a post effect? Looks like a mirror, but I can't tell for sure
