    The “spot the shark one” is great. It took a couple minutes but now I can’t see anything but that damn shark.

    Awesome…intentional, or the danger of linking to someone else’s images?

    That cube would have to be made in three dimensions in order to work!

    These remind me of the excellent Neil Illusions from April 1st, 1971 (via Ironic Sans).

    The one about the shark is really funny to me. Whenever I see one of those images, the only I need to do is taking off my glasses, and I can see those shapes right away, without staring at the point. I just take off my glasses and see the shark figure. Tail to the left, head to the right of the image.

    I get a similar vibe from art gallery remarks.

    It is very cool how the “devil’s tuning fork” at first looks like it has 2 prongs but when you look at it really closely and cross your eyes just so, you see it actually only has two prongs.

    It is amazing how the mind works, just making them round cylinders at one end and rectangular bars at the other tricks your mind into believing that there really are two prongs when in fact it has at least, no more than two.

    I’ve considered doing a similiar site for recpies, but concluded that it was just too mean.

    That was absolutely hilarious.

    My eyes are broken after that five minute stare, pretty sure it gave me a cataract. Still no shark…

    That staircase is completely mad – you could go round and round it forever and never get to either the top or the bottom of your house!

    Haha – this is wonderfully cruel.

    The web is a truly magical place. I love that some human took the time to do this.

  16. magicdragonfly says:

    Weird. No sharks for me. All I could see was pandas. Five of them. Did anyone else see them?

  17. chaoskittenii says:

    Ah, the visual puzzle equivalent of the single entendre.

  18. wrybread says:

    The website itself is an optical illusion.

    this humor is so dry that I cannot laugh while drinking

    Hmm. Is this a gullibility test? Because there’s nothing wrong with many of the things shown. The cube is just a regular box shape. The stairs are not paradoxical. Nah. These are not as advertised. Clever trick though.

      I can’t decide whether you missed the joke or if you are making a meta-joke to troll people to tell you you missed it.

      • Peter Yard says:

        I thought at first it was an in-joke. Then I started to think, “no I think they actually believe this.” There then followed a mind spinning few moments where I wasn’t sure if I was part of a joke or peer pressure was creating a reality. Either way I thought … “stuff it” … so I barged in. Yeah, totally shameless.

    Mighty Optical Illusions is a good one too!

  22. Petzl says:

    I think the site should be called Optical Illusion Illusions.

    At first I thought the Checkerbox illusion was discordant because: here was a real illusion. No, however.  If you color-sample it, he’s doctored it so they actually are different shades (!)

    Actually, the real version of the chessboard illusion is my all time favorite.  I have cut out a square and moved it back and forth, and dang if it doesn’t match them both.

    The board on this site is broken though.
