    Thanks for these, Richard 🙂 These are fascinating and delightful. A few familiar illusions and one or two that, to me, are new, so thanks for sharing more excellent food for thought 😀

    Rabbit and Duck illusion. Really? And why are hands/fingers optical illusion?

  3. Teri says:

    I liked the spiral/back o the hand one the best!

  4. jeffwagg says:

    Would the finger string phenomenon happen if the subject’s eyes were closed? I’m guessing no.

  5. I liked the last one best (the spiral) but I didn’t understand the second one. It said “count the grey dots” but there were only dark grey squares, pale grey lines and white dots.

      Agree about the dots one-never saw anything but white dots. As for the spiral, tried it 3 times and saw absolutly nothing o back of my hand. Disappointed I didn’t see whatever you did Mr. Loony. Envy you.

    I don’t get the ‘hand’ ones (no.3 and no.6). Both look like two people/three hands. Am I missing something?

    The one with the two arcs is my favourite – had to watch it again straightaway!

  7. Christian says:

    The scream at the end scared me! I was expecting something to happen while looking at the spiral and then the ghostly figure appeared and screamed! Scared the bejeezus out of me

    I liked the second and last illusions best.

    Superb. I think illusions aren’t just really neat diversions, they also help demonstrate that reality isn’t just stranger than we imagine; it’s stranger than we can imagine (JBS Haldane).

    Should have waited until nearer Xmas when kids are off school…
    Even then most of them will have seen these

    Are posters honestly saying they’ve never see all of these years ago?

    Some aren’t even the best (or the original) examples of their type, sadly.

    Nice blog you got here. 🙂 I love optical illusions! I certainly like the illusions that can be achieved through visual strokes of the hand. Good job Richard Wiseman. 😀

  13. Indy says:

    That’s really cool-but I would like the black screen at the end to last a little longer in order to get the full effect of the last illusion.

  14. […] Quirky Mind Stuff, by Richard Wiseman (via Matthew Cobb), we have a bunch of illusions, most of them […]

      seen all the reallysame size yhings before or easily guessed them. P. S. What are you supposed to see after spiral-?saw nothing after several tries.

  15. mikekoz68 says:

    What exactly is everyone seeing when they look at the back of their hand, because I’m not seeing it!?

    • Score says:

      If you look at the same point in the spiral for a long enough amount of time, then at the back of your hand, it looks like the back of your hand is expanding (or otherwise distorting)

  16. pendantry says:

    How many eyes you got mike? If just the one (as your avatar — nice one btw), the answer is to your question is ‘hairs’ 😉

    The spiral didn’t do anything to me my hand looked normal afterword

    Hi, the first letter was sent to my billing address, not my shipping address. I do not know if it is just me or other men and women had this trouble but I just desired to let you guys know. It was definitely disappointing not getting the letter where I am right now!
