One of our faithfull visitors, Leo Sakari submitted this awesome optical illusion. We had simmilar ones in the past, like: “Two Monoliths”, “Flowers”, “2 Arrows”, “Lines in a street”, “Soldiers”, “Lines no.2″… but in a way, I think this one shows you the best how your eyes & brain can decive you! This is the description of following illusion: “The black (bold) line in the back seems much longer than the one in the front because your brain assumes it is seeing the effect of perspective. When the background is removed, the lines are seen to be equal”.

    Pretty trippy!
    I had to get out the ruler to make sure they are the same size, I still find it pretty hard to believe just by looking at it that they are.

    are u stupid?? the two BOLD lines are of equal length, try to think 2D for once.

  12. rare_piece says:

    It is too because there is a small change in the two angles, they are not paralell to each other. It is really hard to see though.

    The perspective lines trick your brain into thinking that this is a real world 3d image and uses this to force your mind to calculate that the line on the right is further away and therefore longer. This is componded by the trapezoid tiles that coerce you to think that the left hand line is nearest and three times smaller than the one on the right. Its a great illusion and shows how our ‘common sense’ can be easily fooled. Similar to the classic Muller Lyre illusion. Well done!
