Hy everyone. For today I have prepared simple, yet amazing optical illusion (like I always do :) The Poggendorff Illusion is an optical illusion that involves brain’s perception of the interaction between diagonal lines and horizontal and vertical edges. It is named after Poggendorff, who discovered it in the drawing of Johann Karl Friedrich Zöllner, in which Zöllner showed the Zöllner illusion in 1860. In the picture to the left, a straight A and B line is obscured by a “track”. The A line appears, instead of the B line, to be the same as the C one, which is shown not to be the case. If you would like to check this for your selves, be sure to jump inside this article, and see the explanation example. I can’t beleive I missed posting this one, since it is so perfect optical illusion reperesentative.

That is simply… amazing…
Very nice… Realy confuses me.
sry but i got it after the first look
Simple but neat.
Haha, B looked to me like the one that’s connected to C, but I knew the illusion was it wasn’t what it looked like, so I thought it was A!
I don’t see how this is special actually. I instantly saw that B was the right line.
So I don’t think it’s that much of an illusion, more a test of a technical eye
Nice but i have seen this one before.
Amazing! Tested it with a ruler and all..! Nice illusion!
Hi is spelled H-I.
Oh woowwww… at first, i was thinking that the illusion was going to be just that the A line is the one that its connected to not the b line ‘like you would think’ … but it turns out its indeed the exact opposite! Heh, i like it, that’s nice :D
It does look like it should be the A line! I think its as our mind thinks that the only reason the A one looks slightly off is because of the B one being there and ‘pushing’ it away slightly in our heads, so we take that into account and it looks like A connects with C …. But it doesn’t :)
Nice illusion :D
first comment??
COOL
i dunt see how this is a really big illusion, ur brain tells u its A line and when u take out a ruler and actually extend the line its the B line.. preety simple
Not a very strong illusion, but still interesting.
first ppl
nice… but that illusion is oldielocks
Cool! old tho..1st!
amazing! that’s a good one. i like the illusions that really show how amazing our minds work. thanks
thats freaky
Interesting
That was easily Recognizable for me didn’t need the explanation
It’s so simple..
i think these are really fooling, but they are so UNoriginal that they get kinda annoying. these are cool, but kinda boring, no offense.
mm actually i automatically related the b line to the c line..
anyway..
very classic
1st comment!!!!!!!! i didnt bother 2 look @ the ollusion… :)
looked like B to me anyways
Nice find
Looked like B to me
NIce fine
omg omg first comment.. woohooo
please loser dont do this, as this is not a comment.
good old classic optical illusion :)..
but for some reason this one i can just see by eye that its the bottom one .. needs color.
This great trough its simplicity
First
“Simple, yet amazing”
Absolutely (:
Cool one
Wow, that is impressive!
WOW, I am impressed with this one, yes I did think it should have been attached to line A but it is brilliant. x x
yeah 1st comment, i know that illusion that is OLD!!!< its ok hahahahahahhaha
Brilliant! Realy strange. Haven’t seen this one before.
Personally the first time I looked at it I thought that Line B was the one that connected all the way through, I suppose if I look at Line A a certain way it could appear like that but for my mind it just looks as though it was Line B…
cool
first comment? this one’s really wicked!!! one of the best…
i like this one alot. its in a book i have somewhere (lol) but it alwasy gets me. keep up the good work! and thankyou for giving me something to look at when i first come on the computer :) my first port of call used to be an authors website, but now i come here first everyday!
First?
HAH! I didn’t fall for it :P
FIRST COMMENT, YAY!
cool I was 1st
che cacchio!!!!
Nice work!! I have to confess that I fell into the trap, although my initial thought was that neither straight line could be correctly completed. After some soul-searching, I plumped for line A. Now I have seen the solution, it all seems very obvious… :-)
first comment!
wow that’s a really cool illusion.
1st comment! Yay
1st commend??
no my friend, 1st comment is mine!! you’re late haha
I am a web designer and I noticed this years ago when I first started designing graphics…
i knew B was connected theb whole time. lame.
kool :)
Amazing =)
WOW THATS SO boring
Thats amazing
If you’re good at maths, you should get this right. just look at the angles, the ones that are parallel will run along the right like.
you can get it right if you force yourself to focus on just one line
What in gods name were you smoking, when you discovered this illusion to be sooooooo fascinating David ?
Actually, I see no optical illusion here at all. It appears to be to be exactly what it is. That is, the C line appears to be a continuation of the the B line and that’s what it is.
where can i find Jesus on the cross and blends into the full face of Jesus. i saw it before, but can’t seem to locate it again.
THANKS in advance. stretch
I’m not good at Maths, (I never really was), my point is . . . I’m not even going to try to figure this one out. I will leave it to the experts in Maths.
