Awesome Optical illusion

If you watch the images from your seat in front
of the computer, Mr.Angry is on the left, and Mrs.Calm
is on the right.

Get up from your seat, and move back 12 feet,
and PRESTO!! they switch places!!

I believe this illusion was created by Phillippe
G.Schyns and Aude Oliva of the Univ. of Glasgow.

This proves that we may not be seeing what's actually
there, all the time!!

Excellent Illusion. Though my room is not as big to move back 12 feet but even from a few feet's distance effect was visible.

Freakking awesome !

you dont need to go 12 feet back .. just some 3-4 feet shifting would do.

circle one is easy is easy to guess.....already said dat...da circle in which v r viewin it strait won't move..[also den only any of da circles will move]..as our eye balls are spherical...da image [side circles]reflected on our sides of the eyeball tends to be half...in semi-half.....nd hens its a concentric circles...all da circles...can't adjust in our image in da eyeball.....ok.....u must be confused...but i can giv u a complete scientific explaination 4 dat....but will take a 3 pgs here......BTW iam a Pharmacy student....wait.....lemme refer...yes....pharmacy student...!!

1 more thing see the circle with ur eyes opened as wide as possible.....no circle is gonna move!!...i.e try to c all da circles...niothing gonna move...!!

but researchin on da 1st 1.....!!!

BYE!!!!

There was a thread on Optical Illusions long back .. cant find it now.

OK another good one...

If your eyes follow the movement of the rotating pink dot, you will only see one color, pink. If you stare at the black + in the center, the moving dot turns to green. Now, concentrate on the black + in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a green dot rotating if you're lucky! 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.

I too faced problems in the 1st illusion!

May be bcoz of I'm using Samsung SyncMaster?

But it worked a little bit when I tried to see the illusion by moving up and down as needed :D

Both arent illusions ..

2nd .. is a mind trick .. not an illusion

but good pics anyway

Nov 15, 2005 at 8:17 AM
But alib_i, what is the difference between Mind trick and illusion. I believe, the illusion tricks your mind to see something or not to see something. Thus all illusions are mind tricks but not vise versa. Any way, as i said, here are some more from my old collections:

In an illusion, your eyes plays tricks with you. What you see may not be real. A cow with a (photoshopped) world map doesnt seem to fall in the category .. anyways .. no problem .. no big deal
keep posting ...

Another good illusion I know ..
This illusion was first posted by NikhilVerma ,a very old member of this forum, in a (now deleted) thread
(I still have it's imageshack bbcode from back then, hehe)
It's the best illusion I've seen in my life

Nov 15, 2005 at 5:03 PM
It's very simple....

Just compare the two squares A and B... they are both filled with the EXACT same colour... Even though A appears darker than B...

Nov 15, 2005 at 6:13 PM
This is a real tricky one. This is the only one that I've really failed to understand. Can you explain it in layman's terms how this happens. Got me completely confused.

alib_i #39
Nov 15, 2005 at 6:38 PM
Remove other things from the pic and and you'll see that both are actually same ...
This edited image will make it clear ...

thanks nikhil and alib_i for ur kind explainations. But, what I want to know is what is the exact phenomenon that causes it. If anyone can explain it in layman's terms as I'm not a science student. I love to understand how all this works.
desertwind
Nov 15, 2005 at 8:48 PM
Explanation
In shadow or not, a check that is lighter than its neighboring checks is probably lighter than average, and vice versa. In the figure, the light check in shadow is surrounded by darker checks. Thus, even though the check is physically dark, it is light when compared to its neighbors. The dark checks outside the shadow, conversely, are surrounded by lighter checks, so they look dark by comparison.

Read Full explanation here

Proof
*web.mit.edu/persci/people/adelson/images/checkershadow/checkershadow_double_med.jpg


By joining the squares marked A and B with two vertical stripes of the same shade of gray, it becomes apparent that both squares are the same.

great illusions there, specially first one.
can anyone explain the reason for these illusions...
desertwind
Nov 15, 2005 at 11:45 PM
from close-up, your eye and brain's feature detectors are mostly registering high-frequency information in the picture; from far away you can't see that at all so you use the low frequencies instead. So you can make an ambiguous image like this just by superimposing images made with different Photoshop filters.

Re: Awesome Optical illusion

i hav a test which you will not be able to pass...
read on..

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...

(SEE BELOW)




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.


The reasoning behind is further down.








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.
