Hermann Grid Illusion
While scanning over the left matrix you probably see gray blobs in the intersections of the black crosses formed by the white squares (vice versa for the right matrix). These blobs can be explained by reference to receptive fields and lateral inhibition. -

Checker-Shadow Illusion
In this illusion from E. H. Adelson called checker-shadow illusion, the squares marked A and B are the same shade of gray (we checked that in an image processing program). Like in the simultaneous contrast example above, the environment of a square determines its perceived lightness. -

Ehrenstein's Pattern
In the first image the non-existing circles appear to be very bright.
In the next image they seem to be very dark. -

Bezold Effect: Color Assimilation
The blue or yellow areas adjacent to the green triangles (on the left side) influence the appearance of the green triangles. The yellow makes the green appear lighter and the blue makes the green appear darker. Moreover, it is as if a blending of colors occurs - the green triangles have a light bluish tinge in the yellow environment. This phenomenon is the opposite of a contrast effect where one expects nearby colors to accentuate the differences between adjacent areas.
(You can notice the same effects with different colors on the right side of the image)

Gestalt Laws - Proximity
We tend to group nearby objects.
Is the left center circle bigger than the right center circle?
No, they are both the same size. -
no, we r trying to hallucinate all u folksOriginally posted by SBS9828X:Meltz and PCT u guyz fighting issit see who got more illusions? -
Gestalt Laws - Closure
We are so accustomed to seeing closure that we sometimes close things that aren't. -

Gestalt Laws - Similarity
We tend to group objects with similar properties (color, shape, texture). -
Gestalt Laws - Good Continuation
We tend to assign objects to an entity that is defined by smooth lines or curves. -
Subjective Contours
When you look at the picture, do you see a white triangle floating in front of the black circles? Most people do, although there is not one there! The way the circle parts are cut out, makes us think a triangle is there!
