Well, i had a theory on that one. What I thought about doing but never went through with was getting some inkjet transparencies and laying out a bunch of slide-sized images in photoshop right next to eachother and printing them out and cutting them out with an x-acto. Then mount them in the black mounts i bought. This would actually lend it self to SO many more possibilities.
I'm always trying to find new, creative ways to display photos for my family. One year I did inkjet transparencies cut into circles and put into clear glass ornaments. Huge hit.
Then this year I took the below wall lamp from Ikea . . .
. . . which comes with six different colored plastic covers. I then took the clear plastic cover and put it on the lamp. Then I printed out family pictures on inkjet transparencies and cut them to size, punched holes in the corners and placed it on top of the clear cover. I finally took the white cover and placed it on top of the transparency.
Now, unless you look closely, you couldn't tell that there's a picture there until you turn it on. Watching them open the boxes and turn them on was worth every bit of aggravation it took to get it just right.
So placing your personal pictures on inkjet transparencies, cutting them out, and placing them in the mounts sounds like a grand idea! Quite frankly, it sounds like a marketable idea.
Hmmmm... I think I just might have to take some pictures of my last Christmas project.
