When you scroll down this page, looking at the bridge below it will be as if you looked back between your legs. Check it out! The effect it produces is really confusing.

  19. hottie1213 says:

  20. Saint says:

    mirror. simple as

  21. Anonymous says:

    Oh, get over it, Saint. You just aren’t cool enough to see how cool the brindge is… x.x

  22. Tori says:

    It looks cool! Is that one of those images that was photoshopped to double back on it self (aka mirror it self) I’m just wondering.

  23. Rose says:

    deffinetly no mirror effect cause both sides are obviously different.

  24. Jenny says:

    I’ve seen larger ones like this, where the picture was about 3 times too long for the screen. As you scrolled, the effect was revealed. The concept is cool, but this one is executed poorly.

  25. ME! says:

    jenny, I TOTALLY agree with you. There are better ones.

  26. Vickytoria says:


  27. Duh says:

    Those aren’t coins, you moron.

  28. wezul says:

    I’m surprised some idiot didn’t say ‘cropped.
    Isn’t that what is usually said when something is cool?

  29. woo says:

    I believe you mean “‘shopped”.

    Good god. I can’t believe the level of ‘stupid’ on this page.

    Oh, how Stumbleupon hath failed me…

  30. Tyler says:

    This is stupid. First off maybe you could typer your caption correctly, as to where it makes sense, I never once get a sensation of anything that has to do with legs. The pictures are just opposite each other in direction, what makes it so interesting again?

  31. scylla says:

    hey tyler why can’t you be nice huh?, come on pepole this is a great illusion, if you think that’s stupid well find something better, you….

  32. Ryan says:

    I think that this is just a picture taken with a super-wide angle lens, or a fisheye / wide angle. No photoshop involved, just using a specialty lens

  33. kate says:

    that is hell cool

  34. Alisha and Via says:

    wow….. my brain is.. confused.. i get it but..

  35. Alisha and Via says:

    Ohh…. i havethe right words… Rediculously totally not as amazing as some but still cool brain-numbingly awesome.

  36. Wikto says:

    Dude Awesome!!!!!!

  37. Hopelessz says:

    I get it but it is real confusin XD


    ok heres soulotion,when you scroll to the explanation,you see there is a bridge you are standing on,then hwen you scroll down,you look throgh your legs ,then at the ver bottom,you see you have your head on your bak. Very immposiball optical illusion for some people

  39. me says:

    My head hurts

  40. Anonymous says:

  41. clonious says:

    thats like 3-d!

  42. Klitch says:

    *dizzy* *dizzy*

  43. Blue Blaze says:


  44. Elliot says:

    Really cool!

  45. yewsuf says:

    god, this is lame.
    that’s a panoramic effect.

  46. brandon... says:

    take a look at the picture..look at the trees before you scroll down… see the difference between the trees..

  47. Charissa says:

    It looks as if I’m looking through my legs as I scroll down. Nice one! :D

  48. Anony-mouse says:

    thats really cool. and if u click on the picture it shows the zoomed out view of it which looks cool as well.

  49. Lil' SmilY says:

    WoW This Is sUpeR c00l

  50. raghav says:

    Wow, this is amazing! I want one!!

  51. gggfefqgr says:

    yeah woot woot!!!!!!!EPIC!!

  52. Mary says:

    the other side is a upside down pic of the first side

    • Aster says:

      @ Mary — No, it’s not. Observe closely each side is different.

      The photographer photo shopped this, from several series of photographs of the bridge, lined them all up and faded them together.

      It’s not two pictures of the same side of the bridge.

    • Abagail says:

      it is upside down

    • Ryan says:

      It’s not upside down. Look closely. you’ll notice that the tree branches on one end are different from the ones on the other end.

  53. miranda says:

    that makes my hed hurt

  54. jsld says:

    By what definition is this an illusion?

  55. Shriya says:

    Umm this is confusing, can someone explain? Thank you:)

  56. random says:

    I agree with Jsld it’s a nice bit of computer artwork but it’s not an illusion because you’re not tricked into thinking anything, you’re just seeing what is actually there!

  57. Suor de Sapo says:

    Are we stand up or upside down? That’s the ambiguity wich makes this an illusion.

  58. AppaloosaGirl says:

    Whoa… that is really amazing…. It really feels like you’re turning yourself upside-down!

  59. Aleesha says:

    here it is zoomed out :D bridge.jpg

  60. Jeremy says:

    As a graphic designer, I fail to see why this is an illusion, or the least bit interesting. It’s simply a number of photos stitched together, and the area where the two images blend together isn’t even done that well. It’s blurry and texture of the bridge is missing.

  61. Eric says:

    if you look really close at the middle of the pic the orange pollen things are split.

  62. captian obvious says:

    its just a panoramic shot. duhh

  63. kennt--- says:

    cool, but I think I’ve seen the floss, The picture in the middle area is I think edited and its a bit abvious that its just joint together or something.

  64. BG23 says:

    It is a single shot from a rotating panoramic camera (also called a slit scan or scanning camera) set up with the axis of rotation horizontal.

    There are software based and purely mechanical/optical ones – like they use to take those very wide annual photos of school children (when you can run round the back and get in twice).

  65. owen says:

    cool illusion. just one prob. the middle seems to bulge out. What up with that!?!?!?!?

  66. Bananaman says:

    if yo click the picture, wth?! a mirror maybe, maybe not i dont get it :/

  67. ASIAN says:

    Photoshop. Look closely. :P

    • adumbkid says:

      Not Photoshop! it’s obvious it wasn’t edited after the photo was taken, except maybe for the cropping. It was just a person with a panoramic camera taking a photo of the ground standing in the middle of a bridge. But to be honest, I’d never have the guts to stand there for long. I’d wimp out for someone to come sabotage the bridge.

  69. tanya says:
