  • They do work. It takes some practice to get them though. At first I used a pencil or something to focus on while I made the two dots merge together, stayed focussed on the pencil until my brain “saw” the image behind it, then it sort of locked in and I could take the pencil away. I’ve done so many of them now that I can just go crosseyed to bring the dots together, then look at the middle picture.

    The 3D image works by tricking your brain into seeing a third image that isn’t really there. We’re used to constructing 3D images from two slightly different views; we do it all the time, so the two images are slightly different and when overlaid use the same mechanism to make you think it’s 3D.









  • My hypothesis is that they hide. So I saturate all the hiding places so they have nowhere left to hide.

    When I buy something known for liking to hide, I buy N of them and place them all in a designated “I’ve got N of these things” place (P). Then I put 1 in its home. When it hides, I get its replacement. When that hides, same again. When there are none left in P, I buy N more. Eventually they have nowhere left to hide and finding one is easy. Consequently, they stop hiding.
