Do remember playing with one of these when you were a kid? I remember loving them. We were recently given this viewer from Image 3D along with a reel that we got to create.
I filled it with pictures of them because I thought they'd get a kick out of seeing themselves in the viewer. You can even add 3D text to your pictures. It was easy to build the reel. I think it would make a really fun, unique gift idea too. My nephew was excited to see himself in one of the pictures too.
You could create lots of different reels too. They hold seven pictures (even thought it looks like more).
It makes me smile to see my kids playing with one of the same toys I played with growing up.
