A similar example of ambiguous optical illusions - father and son.

Whole family mind teaser - father with mother and daughter

A landscape and the face of a bearded man.

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

At first sight, what do you see? Do not focus on one region, now look again. You may be surprised

Rabbit and duck one more time.

Swan and squirrel ambiguous image

This is one of classic optical illusions - it is called dancing elephant. Try to count the number of his legs

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

You probably recognize the face in this painting, but if you look at his hair, you'll see that he is fighting a fire-breathing dragon. It's called "St. George the Dragon Slayer"

Stare at the dot in the center of the circle and then move your head closer to it. Neat!

Moving circles.

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 picture below?

 

Visuals

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.

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.

A wonderful moving bicycle illusion.

A hilarious moving curtain illusion.

A nice visual illusion using perfect squares.

Perfect squares one more time.

Fish eating sailboats.

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 paranoids 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

Victory or defeat? Both

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.

When you first look at this, how many colors do you see? Some might say they see 3 or even 4 colors, 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 colors. Since white is not considered to be a color (it is the presence of all colors in scientific terms) we can safely say that there are 2 colors present here! Still don't understand?

And as I began, the same way I end.

 

Eye Illusions

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).

There is nothing moving on the picture.

Another static picture.

Motion is just an eye illusion.

There is nothing moving below.

Boats on the picture are not moving. It's just an eye illusion.

Are there really just flowers?

Is this really a spiral?

Are the horizontal lines parallel? (of course they are)

If you can read the following picture, then you can shout ...

You may read across and upright.
A-B-C or 12-13-14?

This impossible object is called "Devil's Fork" or "Schuster's Conundrum"

Given the wood do you think you could make this?

Or this one?

A realistic photo?

Try to arrange dice like this.

Another interesting building.
