Follow the movement of the rotating pink dot with your eyes and the dots
will remain only one color, pink. But if you stare at the black + in the
center, the moving dot will turn green. (by Jeremy L. Hinton)
If you stare at one yellow dot for a while, the other yellow dots
disappear.
Can you see both the frog and the horse on this visual illusion?
This one is so famous. Turn the picture upside down to see how men see women after 6 beers.
Can you find "the hidden tiger"? Not the obvious one that everyone sees. Look for words in stripes (by Donald Rust).
A mysterious face found on Mars. This is a real photo of the surface of Mars taken by Viking 1 in 1976.
Stare at the four black dots in the center of the image for 30 - 60
seconds. Then quickly close your eyes and look at something bright
(like a lamp or a window with sunlight coming through it). You should
see a white circle with an image inside it.

This one is a classic - no need to introduce.
There should be 11 faces on this picture. Average people see 4-6,
sensible 8-10. The best see all 11, schizophrenics and paranoics 12 and
more. And you? (don't take this one too seriously, I have even heard
that there are 13 faces)
Can you identify a face in this coffee beans pile? Take your time, it is there.
Do you see some squares or rectangles? Really, this is nothing more
than a bunch of lines going in every which direction, but the way our
mind interprets these lines are totally different!
A perfect circle.
Even though the letters are jumbled in the following paragraph, most people have no trouble reading it!

Have you ever noticed a hidden arrow in the FedEx logo? It stands for speed and precision. Check the space between "E" and "x".
Can you read the below?
At first glance, what do you see. Could it be
the word "liar" or is it something more. I would definitely give this
one a second look!
This painting is called "Optical Illusion" - literally - you can read it (by John Langdon).
Victory or defeat? Both (by Veja Magazine).
Try to say the color of the words, instead of actually reading them.
You will find it surprisingly difficult. The right half of your brain
is trying to say the colors, the left half is trying to say the word
itself.This is used by mountaineers to test if they're concentration is
ok. (by J. R. Stroop).
When you first look at this, how many colours do you see? Some might
say they see 3 or even 4 colours, but there are 2 - red and green!
People usually think they see 2 shades of red, but there is only 1.
Look closely and you will notice on one side that white boxes surround
the red boxes, and on the other side, green boxes do! Due to the
placement of these boxes you get the "illusion" of different colours.
Since white is not considered to be a colour (it is the presence of all
colours in scientific terms) we can safely say that there are 2 colours
present here! Still don't understand?
And as I began, the same way I end.
These women didn't scare you, did they (by George A. Wotherspoon)?
Frightened? Of a lady in mirror? Scary, isn't it. It's called "All is Vanity"
(by Charles Allan Gilbert).
Can you see the hidden skull (by Istvan Orosz).
Dr. Jekyll and Mr. Hide scary illusion.
Step away from your computer screen. You should see the two faces swap over!
Come closer to the screen again and they swap again. Spooky, isn't it. This
hybrid image was created by Phillippe G. Schyns and Aude Oliva of the Univ. of
Glasgow. It proves that we may not be seeing what's actually there, all the
time.
Do you see any grey dots where the black lines intersect? In fact, there is
nothing.
Is this really a square?
3 perfect squares.
Which soldier is taller?
Life's too short for the wrong job - that's the name of this great billboard

See the face of a soldier and a man that is bending over on the below <strong>
eye illusion</strong>.
Beautiful scene. But there is something more to it.
It is quite interesting that all numbers can be created by using only two
numerals - 4 and 8.
1st Color Blindness Test - can you see a "12" on this plate?
2nd Color Blindness Test - there is a "26" on this plate.
3rd Color Blindness Test - can you trace a line from one "X" to the other?
4th Color Blindness Test - you should see 58 (upper left), 18 (upper
right), E (lower left) and 17 (lower right).

Who do you like more - women or saxophone players?
Are there really just flowers?
Is this really a spiral?
Are the horizontal lines parallel? (of course they are)

This impossible object is called "Devil's Fork" or "Schuster's Conundrum"
(by D. H. Schuster)
Given the wood do you think you could make this?
Or this one?
A realistic photo?
Try to arrange dices like this.
Another interesting building.
This is definitely one of the best-known <strong>optical illusions</strong>
of all times! What do you see at first glance - an old woman or a young miss?
They are both there!
A similar example of ambiguous optical illusions - father and son.
Whole family mind teaser - father with mother and daughter (by G. H.
Fischer).
Sigmund Freud and what really on his mind is.

Profile of Salvador Dali and a strange woman.
An old couple - see profiles of faces - is remembering the times when they
were young and full of life - see the sitting characters ("Forever Always" by

At first sight, what do you see? Do not focus on one region, now look again.
You may be surprised (by Joseph Jastrow).
Rabbit and duck one more time.
Swan and squirrel ambiguous image (by G. H. Fischer).
This is one of classic optical illusions - it is called dancing elephant. Try
to count the number of his legs (by Roger Shepard).
The tabletops are identical in shape and size! I haven't believed that
either, until I measured it myself.
This one is interesting. Children will probably see a group of playing
dolphins. But adults see usually something else. It's called Message of Love
from the Dolphins (by Sandro Del-Prete).
You probably recognize the face in this painting, but if you look at the
woman's hair, you'll see that it's alive with another an on a horse fighting a
fire-breathing dragon. It's called "St. George the Dragon Slayer" (by Sandro
Del-Prete).
Stare at the dot in the center of the circle and then move your head closer
to it. Neat!
Moving circles. (© Akiyoshi Kitaoka: Used with permission.)
Which central circle is bigger? The left one or the right one? Are you sure?
Is the blue wall in the block or on the block? Is it the back wall or the
side wall?
Is this a complete cube or just 3 sides of it?
Are the diagonal lines parallel?
Most of the people see a donkey first, but if you look closer you'll find a
seal, with its flippers where the donkey's ears are!
Is that a polar bear or a seal on the optical illusion below?
