Visual Illusions


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.
