The red lines in this picture are actually straight, they just appear to be wavy.

    • im cool like that says:

      i have been a regular visitor for a while now,when i see illusions like this, before reading the text, i just go there not straight! but , i have to admit i never get bored of this site! keep up the good work vurdlak!!!

  1. Mat says:

    no they are wavey if u put a ruler to your screen they will not follow the ruler the get further away and dissappear under the ruler

  2. Rayne says:

    Mat’s right. I opened this with paint and drew straight lines; they didn’t match. It’s a cool design though.

  3. Teej says:

    nope sorry guys they are straight…
    get a piece of paper or ruler and hold against the screen, like mat said, and youll see they are straight.

  4. M 2 the H O says:

    Teej is right,
    but i did it a different way.
    go in2 paint and get rid of the background on 1 half,
    then thay appear straight on that side but not on the other.
    and rayne, 4 THAT 2 work in paint u have to make the line 1 size bigger, as it is drawn

  5. alana says:

    here’s a solution, even though im 13, its simple. some are wavier than others while some are straight. its simple logic that proves niether side is correct and that whomever did this is genius! got it?

  6. B34ST says:

    They are sooo straight. The circles distort your veiw how ever you look at it and they only distort red lines.

  7. kxj says:

    they aer staight

  8. 57867 says:

    this illusion was very freaky.

  9. Woahhh! says:

    this is awesome, but ppl, PLEASE, dont try to prove these illusions wrong; they’re not trying to make an argument or anything, its just for viewing some cool things

  10. Josué says:

    I guess that all of you that think the lines are wavy just aren’t straight. :P

  11. i am therrtine says:

    cool I like this illusion. Keep them comin’!

  12. ht qikjfdnasl says:

    The 13 year old is right and I am 11!

    Look – this illusion is very well done. Nothing to discuss about. Infact the lines are straight but offset 1 pixel to the circles’ centers between their junctions. This is why some of you think they are wavy or see them disappearing under rulers or sheets of paper. But that’s not the point. Still the lines seem to bend to the centers of the circles, though they are perfectly straight. Zoom into the picture and you’ll see! What? No software for that? Bad luck.

  14. babyyishh says:

    it’s straight. it’s cool. it’s calleddan illusionn. i agree. stop arguing about it.

  15. anony says:

    open up the big image and look at each line carefully, you will see they are straight

  16. jon says:

    bent, as apposed to bended

  17. Man With A Real Job says:

    I agree with Rhonda. Anybody with enough time to open up paint and take away the background a get a ruler to determine if the lines are straight or wavey has too much extra time on their hands. Get out and look for a real job like 90% of the world!!!!!

  18. Kikker says:

    There is a reason why it is called : AN ILLUSION!!!
    I think that the folks who argue about lines not being straight, need to take a closer look at society and the illusion surrounding us in daily life. so, just enjoy the creativity on this web-site

  19. Jackn says:

    they look straight to me

    Why is it a .gif?

  21. Elliexx ANIMALS ROCK!! says:

    yeh they r straight – the circles distort your view of the lines.
    y do some ppl say that the lines r bent. if they werent straight, y would they have put this illusion on this website and told us that they were straight? if u get wat i mean.

    kl illusion!!

  22. Danger Machine says:

    They are bent. But that illusion does work without cheating

    If you compare the two squares, one is pointy while the other is rounded. They are not straight

    I don’t know about you, but when I tried that, the Paint line folowed the line wich was alredy in the picture.

    if you highlight the pic the lines will be straight

  27. Anonymous says:

    Since the moment I saw it, I saw that the red lines are straight. I don’t see at all how that can be confused as wavey.

  28. smoky says:

    hmm should it not be “bent” lines as opposed to “bended”?

    Ok there is a nail in the hammer which the weight of the head pushes the other end up… it’s all because of the nail the little shiny thing like an inch from the metal.

  32. Me, Myself, and iPod says:

    i put a pencil on each side just to see if they were straight and it PROVES that they are straight! and I’ll tell you the truth… I am only 11 and i could figure that out! EASY…

  33. HHHhhh says:

    you often spell bent wrong. there’s no such words as bended

    I saw them straight in the first place =/

    Does this mean I can be in MENSA?

  35. Will C says:

    some are straight, some are wavy

    Every other square bulges out from the paper showing a sliver of the white background. Every alternating square bulges under the paper showing no red line on some lines…

    other lines are perfectly straight.

    i sorta already got it, but it’s a good(but easy) trick.

  37. JetJagger says:

    I am a graphic designer who opened this image in a photo editing program. The lines are, in fact, bent in the above image. The “diamonds” that appear to have convex walls are, in fact, convex. The images that appear to have concave walls are, in fact, concave.

    I have seen this illusion on paper, and it works. It is not intended to be viewed as a pixelated image due to the “interpolative” nature of image editing programs (such as the one that was used to create the image) and the “interpretative” nature of monitors which displays images in pixels to emulate continuous tone but, in fact, is not mathematically accurate due to resolution factors.

    I assure you, the red lines are not straight, and you cannot accurately validate this by using a sheet of paper held against your monitor. You need to copy the image to your image editing program, zoom in, and draw point-to-point lines.

    Have fun with it.

    ‘BENDED’? How about bent? LOL

Speak Your Mind
