I've never been able to see them. I was googling them last night and I thought I had one figured out. I was all "oh, it's a crowd of people! I think I see it!" Nope. It was Saturn. lllllol. I give up.
I can. Usually in a couple seconds. They were my favorite as a kid!
I saw a music video once that was a magic eye thing. In the beginning, it does an ok job of showing how to relax your eyes. It would work with the still pictures.
The crossing eyes thing doesn't work for me. It makes the images inverted, for some reason.
Also, kind of funny story. I've been talking to a guy for awhile. We were making small talk and hidden talents came up somehow. I said that seeing Magic Eye puzzles was one of mine. He made one and sent it to me the next day - it was asking for my phone number. lol.
I gave it to him, because it made me laugh and it was clever. (And he's really cute/nice. But the magic eye got major bonus points.)
