See it? It is called a collage frame. The brand is Umbra and I could only find it at Bed, Bath and Beyond. The photos attach with tiny clips and you can arrange the photos however you like. It came with 12 clips and a mounting thingy which would have required us to make a big hole in the wall. We declined to do that and used a regular picture frame hook. Not as attractive as the mounting piece they provided but easier.
I printed out some of my favorite photos as well as putting up the photo card of the Baby Princess. So we got 3 Baby Princess pics, 2 pics of my husband with each of the cats and my favorite photo of me, when I was 6, smack dab in the middle there. I actually have the original of the photo of me but it is larger.
The fun thing is that it is easy peasy to change the photos at will or whim and whimsy. You can clip just about anything you want up there. There are all shapes and sizes of these collage frames, available from many sources, I just fell for this particular one. Of course you crafty folks could probably make one.
