The ‘brown’ square in the centre top, and the ‘orange’ square in the centre front are exactly the same shade of brown.
Don't believe it?

The SCINTILLATING GRID – black dots appear at random intersections
Focus on a single intersection, the dot does not appear. The dots disappear if you are too close or too far from the image.

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

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?
If you find the face in 3 seconds or less, the right half of your brain may be more well developed than most.

This is called an "impossible object," which means that it's impossible to build.
But drawing it is not impossible, as you see in the image.

Julian Beever creates pavement art. Many of his creations are optical
illusions, such as this one, where he appears to be perched on a ledge, waiting for Batman and Robin to
climb the building and rescue him.
In reality, there is just pavement in front of him – the rest is a 'trick the
eye'.

Can you see the Shark in the picture above. The trick is not to focus directly on the image but
try to focus on a point through the image. With a bit of patience and relaxation you CAN do it.
