Do the straight horizontal gray lines look curvy to you? Hold up a piece of paper to prove that they are straight and parallel to each other.

i think the question is supposed to be "do the horizontal lines look slanted?"

Posted by bigSWAFF_69_ on Oct 17, 2005

Well, "Slanted" is a better word than "curvy".......

Posted by cdrock on Oct 17, 2005

slanted also works, but they were curvy to me to

Posted by smilingpatience on Oct 17, 2005

That trips me out a bit, the lines can be slatned, straight or curved, wierd.

Of course they LOOK bendy. But I know they aren't cause otherwise it wouldn't be listed as an optical-illusion.

Posted by FutureMD on Jun 18, 2007

I liked this illusion a lot. It is funny what just a little staggering of blocks can do to perfectly straight lines-a little philosophical, huh?

Posted by on Jul 20, 2009

technically, it isn't slanted or anything.
Simply, the "checkerboard"
isn't exactly formatted as it should.
The row under each other is simply
placed out of the order therefore
making it look slanted.

Posted by pokegirl09 on Nov 28, 2009


Posted by bloop on May 05, 2010


Posted by dylan99 on Jul 23, 2010

if you move page up and down,black lines will "dance"

Posted by Mathgeek007 on Nov 06, 2010

Good job. Now, go to the first trivia ever made.

(This is for The Amazing Race)

Posted by Candyhook on Nov 19, 2010

they looked straight

Posted by Me-waz-here on Jan 08, 2012

If you look at the side, or the ends of the lines, they are perfect.

Posted by cool_gal on Jan 13, 2013

I don't even need a ruler to tell these lines are straight. The lines are just at a certain angle that makes them look slanted or curved. Great illusion, Jake!

Posted by Proph on Jan 27, 2014

perfect one!

Posted by stitch-ex626 on Oct 26, 2014

WOW!!! that was a tricky one but I used a chocolate bar instead for a piece of paper.LOL
all of u are awesome thank u for not cussing

Posted by XtinaF on Jan 29, 2015

This freaks my mind

Posted by JeremyRedhead on Feb 11, 2015

Interestingly enough,
if you scroll the page up & down a bunch,
it appears that the lines are moving back & forth.

Posted by jonahbabe on Apr 27, 2017

Amazing! (y)
