Rainbow illusion

After painting walls and polishing floorboards yonks ago, we've finally got busy hanging pictures at last. This morning the sun streamed in through the cut glass in my front door, making rainbows on the wall and on this photo that I love, and that we had only hung last night. I love the illusion and the photo-within-a-photo idea, so I just had to blip it!

(The original was not taken by me, and it has no title or name on it. All I remember is that I bought it at a small exhibition several years ago).
