    I have this problem all the time. I’ll be looking at a photo of moon craters, or a volcanic caldera, and my brain will insist on seeing them as popping out instead of sinking in. I’ll have to flip the photo before I can see it correctly. Even then, sometimes my brain will try to flip it back the wrong way, even when I know what I’m supposed to be seeing.

  3. Whew! Tricky one! At first my brain kept INSISTING that they could NOT be the same image! It wasn’t until I actually took my kindle out of the stand and manually moved it around for flipping that I could finally get it!

    VERY nice!

    • Dear Bluebird and Michael,

      Optical illusions can be very enticing and fascinating to experience. I have categorized thoroughly various optical illusions and included hundreds of examples in my special post at

      https://soundeagle.wordpress.com/2017/09/28/optical-illusions/

      This said post covers the topics of optical illusions quite comprehensively with more than 200 examples. Given its length and scope, it will take some time to load fully. In addition, please be informed that you might need to use a desktop or laptop computer with a large screen to view the rich multimedia contents available for heightening your multisensory enjoyment at my websites, some of which could be too powerful and feature-rich for iPad, iPhone, tablet or other portable devices to handle properly or adequately.

      Many of the excellent examples included in the post are quite astonishing, even to the point of defying belief.

      Our visual apparatus has a lot of evolutionary quirks. One of them, the perceptual time lag, to which I refer as neural delays averaging 100 milliseconds, has been responsible for many fascinating optical illusions, arising from the compensatory mechanisms of the visual system to “see into the future”.

      As you can see in my said post, some optical artists have designed graphics called op art or optical art, which can give the sensations of seeing something moving, vibrating, pulsating and/or rotating, even though the generated images are truly static.

      Happy November to both of you!

      Yours sincerely,
      SoundEagle

    It has to do with the angle of lighting AND the shadows, which is how we get clues for depth out of a 2D image. Welcome to the complex human brain!

    This is driving me nuts! I keep wanting to disprove it but I can’t.

    I can sometimes see each individual block in both photos. Then I see the underlining wood and it turns upside down. Very strange indeed.
