Awesome Optical Illusions

Scintillation Grid:

It comes with different names, but Scintillation Grid is probably the right name. Thanks to Elke Lingelbach of the Institut fur Augenoptik Aalen in Germany, this optical illusion is available to us. Illusion: Just count the number of black points!
The Amazing Dots:

This illusion is designed by Jeremy L. Hinton of Bristol, UK. What is the point? Just concentrate on the mark ‘X’ and you will see start seeing a green dot rotating instead of pink and then these pink dots will disappear and only green rotating dot will remain.

The science behind it is ‘Negative Retinal Afterimage’ or after image effect.


Dragon Illusion:

Getting millions of hits, this is the most wonderful illusion you will come across. Put it on a table and move around it, you see the head of the dragon move across.

Theory is that on viewing a solid object, brain figures out how the object we are looking at will behave. But dragon gives us wrong impression or to our brain. The thing is shape of it, we misinterpret it by assuming that nose is pointed towards us but actually the head of the dragon is concave.
Square:

The letter ‘X’ seems to be made of different shades of colur actually it is not. It is made of single colur and can you guess which colur is that?


Mona Lisa Illusion:

Two most famous paintings in the world placed up side down. Can you tell the difference?

If you spin the image right way up, you find that one of Mona Lisa looks ghastly. The reason is that your mind is not used to looking pitures up side down, thats why it could not diffrentiate between two pictures

ROTATING DISCS

The disks appear to rotate because the concentric gray circles give the impression off spirals.
Simultaneous Contrast

We see shift in identical colors when there is a different background on which they are framed resulting in a phenomena called “simultaneous contrast”. This results in a a variety of affects on how we see objects.

For this illusion, look at the diagrams below. Do you see different colors on each side of the stripe? In each picture, you observe that squares present at the left side of the image are more darker compared to those at the right. To clearly see the simultaneous contrast effect, watch the images from the side of your picture.
Kanizsa Triangle
Let me guess, you perceived a white equilateral triangle in the above picture. But, as a matter of fact none is drawn. This effect is called as illusory contour.

You will also observe that the white triangle is more brighter than the surrounding, but in fact it has same level of brightness as does the background have.
