**The Optical Illusions Thread**

[Chalex4]

Some of you may have seen these before, but I definitely think they are worth posting here for all to see.

Please add your favourite optical illusions below, it doesn't matter if you bump the thread!

ALZHEIMERS' EYE TEST

Count every ' F ' in the following text:

FINISHED FILES ARE THE RE
SULT OF YEARS OF SCIENTI
FIC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS...


Once you have finished counting, please look here:

HOW MANY ?
WRONG, THERE ARE 6 -- no joke.
READ IT AGAIN !
Really, go Back and Try to find the 6 F's before you scroll down.

http://www.atkcommunity.com/chalex4/tricks/brain.gif

The reasoning behind this is in the next spoiler tag, make sure you have finished searching.

The brain cannot process 'OF'.

Incredible or what? Go back and look again!!
Anyone who counts all 6 'F's' on the first go is a genius.

Three is normal, four is quite rare.


THE SPINNING WOMAN

http://www.atkcommunity.com/chalex4/tricks/woman.gif

Look at the spinning woman, if she is turning right your right side of your brain is working. If she is turning left, your left side of your brain is working. If she turns both ways for you then you have a 160 or better IQ.

-------------------------------------------------------

Awesome or what? I only counted 3 Fs in the passage, but can easily see the woman turning both ways.

How about you? (Don't make up stuff just to sound clever please!)

[Calneon]

I only see the woman turning right, does that mean i'm stupid?

Demoralizing...

I actually counted 6 Fs, but i'd already read it before so I was looking extra carefully.

Read the last paragraph very easily.

[Chalex4]

Read the last paragraph very easily.

Yeah, didn't find it a problem either. Please post your own below!

[Chazlene]

I counted 5 F's to begin with, missed the last 'OF' for some reason.

And the woman is spinning right for me.

[Bloo]

I counted six F's because I decided to read it v.e.r.y. s.l.o.w.l.y and thus probably screwed up what was meant to happen.

The woman is spinning right, which is odd, because like, under 1 in 5 left-handed people use their right side of their brain mainly. (Though all those statistic are kind of bull, because right-handers are meant to use the left side of their brain mainly..)

And yeah, the last paragraph is easy because i've seen it before on Brainiac. :)

[Friend of Wander]

I counted 6 Fs first time, and I had never seen the illusion before. ^_^





I'M A GENIUS! :D

[Midge]

6 Fs and spinning to the right
vox had shown me the last paragraph before too

[VoX]

Seen the last one before and counted 3 F's, then 3 again, and then finally 5... Fail?

[Chazlene]

Yeah, I've seen the last paragraph before somewhere, but now when I look at the woman she's spinning left...

[Chalex4]

Ok, here's a few more another:

Human Faces

http://www.atkcommunity.com/chalex4/tricks/faces.jpg

How many human faces can you find in this picture?
There are probably more than you first see, so keep trying.
How did you do?

Seeing 4 or 5 is average
6 or 7, above average
8 or 9, very observant
10 or 11, extraordinarily observant

The Man in the Coffee Beans

The "illusion" is that this is just a picture of coffee beans; but it is not. Can you find a man's face among the beans? Some say that if you find the man in 3 seconds or less, the right half of your brain may be more well developed than most.

PS: This is not a trick. A man's face is really hidden among the beans.

Pink Dots

If your eyes follow the movement of the rotating pink dot,
the dots will remain only one color, pink.

http://www.atkcommunity.com/chalex4/tricks/pinkdots.gif

However if you stare at the black "+ in the center, the moving dots turns to green.

Now, concentrate on the black "+" in the center of the picture. After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.

It's amazing how our brain works. There really is no green dot, and the pink ones really don't disappear. This should be proof enough, we don't always see what we think we see.

-------------------------------------------------------

The faces one is my favourite I think (out of these 3), especially since it is hard to see any faces at first glance. I think I have seen them all now though, assuming there are only 11.

Oh, and finding the guy in the coffee beans is fairly easy.

[Toxic]

I counted 6 F's because I read it super slow (: I also saw the women spinning to the right, then when I scrolled back up she was spinning to the left o:

As for the face in the rocks one, I counted 11.

[Chazlene]

That pink dot one is my favourite, really bizarre when the pink dots disappear. I managed to get 9 faces on the first pic, but there's also areas where I think there is a face, but can't perfectly make it out.

I think the reason why a pale green dot appears is because our brain gets fed up of seeing lots of the same colour, so forces us to see the opposite of that colour.

[Bloo]

I saw 8 faces on my first try. And err, I found the face in the beans quite quickly and the dot one doesn't work because when I stare at the + the pink bits don't disappear!

[Calneon]

8 Faces with a very quick look.

Took quite a while actually, couldnt see it at first so I skipped, then found it as I went back. Probably because I thought the face was made up of multiple beans, so i was looking for patterns in the beans, not an actual face on a bean.

Dot one is really really wierd how the dissapear.

THE SPINNING WOMAN

http://www.atkcommunity.com/chalex4/tricks/woman.gif

Look at the spinning woman, if she is turning right your right side of your brain is working. If she is turning left, your left side of your brain is working. If she turns both ways for you then you have a 160 or better IQ.





Found this, it's all about the spinning woman illusion:

http://www.news.com.au/heraldsun/story/0,21985,22556281-661,00.html

Just from that list I would say i'm right-brained. :D

[Trigger]

Well i only saw 3 F's first time and i can get the spinning women to change which side she spins just by thinking about it:confused:, only saw 8 faces and i had allready seen the face one.

The Pink dot is the best in my opinioun, they all just show how fragile our perceptions of everything is :eek:

[Marshy]

I can make her change sides aswell :S am i clveres

[Friend of Wander]

I saw 11 faces on the first time, and couldn't find any more after that...the coffee beans however...WHERE IS THE FACE!? D: I can't see a thing :(

[VoX]

Face is near the bottom left.

Saw 9 faces first time too :p.
