Test your brain with illusion optic

The Ebbinghaus illusion or Titchener circles depicts relative size perception. Which central circle is bigger? The left one or the right one? Are you sure?

In this café wall illusion the parallel straight horizontal lines appear to be bent. Important is that each "brick" is surrounded by the grey line, so a colour in between the dark and light colour of the "bricks".

Motion is just an eye illusion. (© Akiyoshi Kitaoka: Used with permission.)

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

Try to arrange dice like this.

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 brain teaser is used by mountaineers to test if their concentration is ok. (by J. R. Stroop).

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

4th Color Blindness Test - you should see 58 (upper left), 18 (upper right), E (lower left) and 17 (lower right).

Color Blindness Test - can you trace a line from one "X" to the other?

Hering Illusions suggests that the horizontal lines are bent, however, the distortion is caused by the background that simulates perspective and thus false depth perception is created. (by Ewald Hering)

Are the diagonal lines parallel? Of course, they are - angle of the short lines helps to create the impression that one end of the longer lines is nearer to us than the other end. (by Johann Karl Friedrich Zöllner)

Slanted lines in the following illusions produce a great effect. Both rectangles are parallel - you can take a ruler to check it out.

The tabletops are identical in shape and size! I haven't believed that either, until I measured it myself.

A nice visual illusion using perfect squares. (© Akiyoshi Kitaoka: Used with permission.)

3 perfect squares.

Static circle but if you not concentrate it can move. try it.

Most of illusion I take from website below that i think interesting. If want to see more you can refer below website. Very interesting and we are not thinking about that..
