Oh my gosh, when I was a child I remember going into a shop at the beach which sold all kinds of holographic images. And I remember a couple of them had pictures of things like a telescope or binoculars, and you could actually look into them! I've been searching for a while for any kind of information about these things, and I was almost ready to believe that I had just imagined it. But there is the same thing just 1 minute into this video!
