We got ourselves another simple, yet interesting illusion. This one was also submitted by one of our fans; Simon David posted it, plus provided description. Do you see imaginary black stripes?

Simon: “A simple illusion, black strips running bottom-left to top-right.”

    aww this one is pretty weak for me. i can just about see the stripes, but very faintly.
    first ilusion on here i`ve not been able to see properly. :(

    Same here. Weak illusion.

    Now I have a question. Why is there a delay for our comments to be posted? I thought someone had to review them first, but it seems anything gets past. Cursing, non-sensical posts, spam, everything. I mean WTF is up with all those “Very nice site. Thanks!!!” posts? This is a weird comment system.

    so! I can do that on my computer

    Don’t see any Big Deal

  22. At_Home_sick says:

    I just wanted to point out that if you stare at it for long enough, thick black stripes appear on the white around the picture running the opposite way.

    If you try, you can remove the black lines from your mind, for they are not there to begin with, hence optical illusion, the red lines trick your mind into seeing black lines.

  28. Frank says:

    Hey guys, might be me seeing this website for too long, but do any of you see black circles in the middle of the orange lines, right were the “black lines” cross?

  29. Cherry Blossom says:

    That is VERY well done! The black lines don’t even really exist!

  30. because the back ground is black and i can see it under the red stripes

  31. MrsAtticusMitchell says:

    thats the best one i’ve seen yet on this site!!

  32. John Steven Hoglund says:

    1. No one mentioned the jumping red stripes.
    2. No one suggested a cause for the appearance of black stripes.

  33. Jill says:

    How does this work???!!

  34. You Can't Know Me says:

    The red stripes cover the intersecting corners of the blue lines, so your brain interprets there’s something else covering the corners, disregarding the red stripes.
    Since the red stripes already run from top-left to bottom-right, the imaginary stripes run from top-right to bottom-left.
    Furthermore, the stripes are black because the background is black.

  35. You Can't Know Me says:

    I have JUST one question; why imagine there must be something else covering the corners when the red stripes have already done that job?

Speak Your Mind

You can add some images too.
