    WOW! I’m not sure if that was camera trickery or an optical illusion.
    Regardless it gets a grade of – C.
    For – COOL! Maybe – WC for WAY COOL!

  2. Ultrarebel says:

    Awesome. Did not see that one. Looked like magnetic trickery first. Really cool.

  3. Steve Ulven says:

    Very cool! I’m glad they showed how it was done, that would’ve really got to me if they didn’t.

  4. mrps says:

    I’m impressed!! very goood!

  5. PeaceLove says:

    Wow, beautiful. Reminds me of some of the stuff Jerry Andrus kept lying around his house!

  6. Can we ever believe what we THINK we see?

  7. LongSteve says:

    Awesome, one of the best illusions I’ve seen. Keep finding these great images and videos please.

    Simply amazing how, even KNOWING what it is, my brain wants to take it at its initial “face value” and marvels at the upwards motion!! Wow.

    I built some stuff by Jerry Andrus, wish we had the plans for this one !!
    Thanks !

    Huh, it didn’t impress me so much.

  11. ZenMonkey says:

    The part that’s so cool is, as KatyM says, the fact that my brain refused to see it the “right” way even after they showed the illusion. I just can’t manage to see it correctly. That’s neat.

    Very nice illusion!

    I found this document where the author explains the trick:

    It would have been nice if he had included some drawings!

    Trompe-l’œils, gotta love them.

    WOW this is just incredible! I still can’t believe I saw what I saw 😀

  17. mickeyd says:

    Really great! Want to try to reproduce that!

    If you notice on the two small runs the balls travel a lot faster toward the centre. Hence, they are steeper in height but look equal to the centre because of the perspective illusion.

  19. Steve Page says:

    It’s well-done, but it’s just a variation on the Ames Room illusion, which incorporated a similar idea in its original design. This is the psychology equivalent of a cover version; psycharaoke, perhaps?

  20. D says:

    I’m impressed, but certainly wouldn’t use the word “stunned”. 😀

  21. Nikki says:

    Is it supposed to be obvious *why* we see the slopes the wrong way or is nobody interested?

  22. B. says:

    That’s great. Reminds me of Chop Cup on Youtube.

    What if the slides were made of a stretchable material (elastic maybe) and the center column could be moved (maybe it’s just held in place with magnets). This way the whole platform could be rotated for he camera as subtle adjustments to the center column are made, thus keeping the illusion intact.

  25. JE says:

    I thought a very clever bit was that the edges of the sides didn’t meet, so there was a little triangular gap. That really added to the illusion that they were sloped down and away from each other.

  26. erikthebassist says:

    The center column holding up the middle of the ramp is swept towards the viewer at the base in the first image. They are using perspective to trick you in to thinking it is vertical. Your brain fills in the rest, assuming that since that column appears to be the tallest, the middle of the ramp must be the highest point.
