Visual Puzzle

I often look out for visual puzzles, where it's not quite clear what's going on in the image. But of course, we all see things differently and I wonder sometimes whether the confusion I intended has any effect at all!

And like those puzzles where it could be the outline of two faces or a vase in between them, some people can see one thing, but not the other and vis versa.

Reflecting (pardon the pun) on this image, I think maybe the reflections aren't quite sharp enough to cause doubt. But it appealed to me.
