Relative Sizes category consists of hundred interesting optical illusions, but the problem occurs when you start understanding them. When you see one, it is if you have seen all. All of them start to look the same. This is probably why none of them were posted lately. Well, this time Alan Mountain ensured we get ourselves some fresh, and even more complex material! In the photo below you can see Jochen and Marita Wiesner interact with an installation at an exhibition called Tour of Senses in Dresden, Germany. As you see, the exhibition deals with senses and plays with our perceptions. If you don’t have a clue how this optical illusion was produced, you should check this hint. If you are still having trouble, you are allowed to see the solution.

Gullivers Travels Optical Illusion

"Relative Sizes" optical illusion can somtimes be as complex as this one!

    wow, i had no idea how it was acheived! I’m glad that you posted the solution

  2. lacey says:

    wow this one is awsome

  3. Tim says:

    Oh, that is seriously cool. I knew the concept, but never thought about it being done in exactly that way. Very cool.

  4. Lisa says:

    This one isn’t as good because you can see the shadow of the post without the top part on it. Makes it a little obvious where she’s sitting.

  5. sal says:

    you can see the shadows of the “chair legs” ending with no seat at the top and the shadow of the chair back begin on a totally different plane.

  6. Care Bear says:

    Whoa! Good one. How’dja dodat?

  7. Tyler says:

    The seat she’s sitting on is actually on the floor a little bit away from him, you can see the shadow of the left corner of the chair (near her right knee) on the floor. What a cool exhibit though!

  8. Alex says:

    figured it out look at the top of the chair, not the legs, they are further back and the legs are closer to the man. If u r havin trouble look at her feet where they touch the chair.

  9. David says:

    Wow! this one is very good,Top quality

  10. Steve Buchok says:

    If you notice, there is no shadow under the chair. That should give you a good hint as to how this is done.

  11. EMH says:

    Look at the shadow of the chair leg on the man’s right leg. It ends right there and there’s no shadow of the seat or the sitter. The lines between the chair legs and the seat look a little hinky too, but this is still a great illusion.

  12. Mr Average says:

    Another good one. I had to stare at this for a while even after seeing the hint. Another hint: the shadows give it away.

  13. Samuel says:

    easy, it’s in the legs of the chair

  14. palmino says:

    Look at the shadow of the chair’s legs, the platform is behind. They should had paint the rest of the shadow on the ground. Great anyway!

  15. FixitDave says:

    You can see that the seat is not attached to the legs, need better camera work..good attempt though

  16. Marty says:

    The best clue is the shadows.

  17. Facebook User says:

    fake or is its real, looks so photoshopped!?

  18. Mark says:

    I noticed that you can see the shadow of the chair legs (without a seat)in front, and the shadow of the chair back, back by the window.

  19. Moony920 says:

    Oh this isn’t that bad.
    it’s just the matter of POV.
    Her Seat is Actually on the floor.

  21. Ds says:

    Yea, if you look at the shadow of the chair legs, it cuts off where the man should be.

  22. Ben says:

    Wow- That tricked me for a second!

  23. Alyssa says:

    No matter how many giveaways….its a hard to nderstand illuson

  24. jojo says:

    Pretty easy…the concept of the illusion is similar to this..


    …the chair just has legs..the women has the seat on the floor far behind..;)

  25. Facebook User says:

    Beyond a shadow of a doubt~ or the shadows of doubt-though at first this looks like a familiar type of size/distance illusion, the execution is original and clever. A real treat!

  26. Michael Tro says:

    i was able to find the solution (with out looking the the solution page) by looking at the shadows

  27. Ramon Teja says:

    She should be looking up. She is looking at him and he is in front, closer to the camera.
    If she looks upward, faking it, it would have been much better.

  28. Melissa Beall says:

    While I do agree the shadow gave it away a bit, this was clearly enough a masterful enough optical illusion for Peter Jackson to rely on it for about 50% of The Lord of the Rings, and this is an excellent display of just how easily it can trick the eye.

  29. Aiman Amani says:

    I agree with Ramon Teja but whatever it is, it’s just GREAT! I love this site!

  30. Chrıs Anton says:

    That tricked me for a second :D

  31. Crenshaw Yeo says:

    oh DAMN!

    i figured it out about a second later, but thats an awesome illusion

  32. Waggers says:

    It looks a bit photoshopped coz if you look carefully where the legs are it just looks a bit off and the shadow of the chair has no legs

  33. Martin says:

    This is really cool, i found out the illusion by looking at the shadows right by the seat and found that they looked almost as if on the ground… well it was haha, but otherwise, this is still incredibly done

  34. me says:

    ohh i get it. LOL

  35. nobody says:

    ooooooh i see it the platform shes sitting on is on the ground a little bit away and the chairlegs are on the silver thing hes standing on it was at the camera angle that made it look like a chiar!!!! omg awesome i love it

  36. el-j says:

    the woman is sitting in the seat without legs in the background, while the man is standing on the platform with the legs of the chair on the foreground, at an angle the chair becomes one whole with the illusion that the woman is smaller when she is actually farther.

  37. Moo Moo says:

    Wow thats so cool
    How do they do it ?????

  38. DAvid M!7@n says:

    easy trick just use the tool named fotomix

  39. baster says:

    i never seen this illusion before, but i knew straight away how to do it :D great illusion!

  40. kevin says:

    in the first picture. the seat isn’t attached to the chair. its on the floor like in the second pic. but in the second pic they make it obvious and they move the camera.

  41. exinco says:

    gulliver nice movie. this illusion was stunning

  42. Jemima duck says:

    Top of the chair is in the background. Needs better camera work. Sorry. :/
