This would, in fact, be a mirror. By coincidence it happened to be reflecting back an image of me at the time I was photographing it, making it appear to look like me. But appearances, as any good stagehand can tell you, are often misleading. If you look at the upper right of the photo, you'll see there's a big knob on the mirror. There's no such big knob on my hand.
So it looks like me. But it's not quite me.
