Shepard’s Mona Lisa Illusion


Illusion below is something better known as Roger Shepard’s “Turning the Tables” illusion. Basically it’s the same thing we featured multiple times, using different motif. Look at the two Mona Lisa’s below. If I told you they had an equal surface area on their tops, you’d probably take it for granted. But what if I told you that they also were identical in both length and width?! If you don’t believe me, try and measure them for yourself. Below image is given so you can print it out, make a cutout of both paintings, and reposition them one over another… Do they fit nicely?

    Fabulous illusion! I indeed had to measure them.


  • diane

    Cool .Lots of Mona lisa.

    I believe You ;-)

  • Joe

    Wrong. I cut them out, and they do not fit on top of each other. They are NOT equal in length and width. Incorrect on this one.

  • Quinn

    That is messed up!! Good one!

  • Maddie

    I really think you should do something about printers-people who don’t have printers can’t print something important or whatever out. I wish they would design a computer with a built in printer!
    Anyways-Cool illusion-but it was too easy.

  • Fifi

    I like this, makes my head hurt!

  • Pulchra55

    I didn’t believe it until I measured it…it’s true! Nice.

  • eric

    no – they dont
    right one is 1 millimeter shorter n 1 mm wider

    • Watcher

      eric is correct. there must have been a skewing of the original image in posting it on this site. the left one got elongated and the right one is fatter. (or they both became elongated on the virtical sizing)

    Actually, what surprises me is neither the length nor the area (I ever know this illusion), but the parallelism. Don’t you have the feeling that the paintings are trapezoidal ?!

  • Tara

    Measured it. Totally not the same size.

  • minecaricature

    fantastic way of making the mind think they are 3d!

  • Melissa

    Don’t like it sorry .
