Parallel World Illusion


An interesting look at the parallel world where anything is possible! What you see below is a successful variation of the “Folded Chessboard” classic painting done by Sandro Del Prete. Titled “The Terrace” this illusion became so popular around the net, that not many are aware of its original author – David Macdonald. The illusion by David surpassed Sandro’s chessboard in terms of internet popularity.

    When I see these impossible stuff only on thing comes to my mind
    Photoshop :)
    On the right side there is a ladder
    You can see on the top the man is facing towards the picture
    And the man in the bottem is trying to climb facing you

    Anyone saw that starfish in that birdbath?

  • rabbit

    It would be interesting to see how the artist would have connected the top fence with the bottom fence but alas they are cut off at the side of the art.

    Thats nothing. You need to see Convex and Concave by M.C. Escher.

    I have to say that this is my favourite illusion of all time. It’s just brilliant.

    Well, it’s my favourite illusion until I find a better one on Mighty Optical! I love your site, keep up the good work!

  • AmbO

    this reminds me of monty python and the search for the the holy grail.
    when they first come up to the castle and all that.

  • cacao bean

    imagine what it would look like if there was a building there!

  • Ai

    Very classic idea, but nicely rendered.

  • Lai-Lai

  • brionny

    one side is curled up and the man climbed at the opposideof the ladder and so on

  • SuperGanj

    This is really cool. I would love to watch a video showing an artist creating this illusion.

    • Thanks for all your kind comments on my illusion. A couple of people asked how this done and one to see a video of how it is done. You can find a video of me at work on a different illusion (in French I am afraid) on my website Enjoy.
