The Sunday Challenge this week:: Since it is so close to Halloween let's "do something creepy, scary or spooky" with the added challenge being that a mirror has to be part of the image or used to create the image.
I have a small obsidian stone ornament on the mantelpiece, which shines gold in some light and black at other times. He isn't threatening at all, but I was very surprised by the effect in a mirror. I used Silver Effex to create this strange illusion.
