According to you, which red bar is largest ?
Is it the right one ? Of course not !

they are rigorously identical, check by moving the red bars with your cursor (below).

This is due to the perspective. The effect is increased by the checkerboard because we estimate the size of the red bars compared to the squares

You can move this to check by your self

The two tables illusion
the stick optical illusion

Are the two tables (blue areas) identical ?

This is unbelievable, the two blue areas A and B are absolutely identica !

There is no fake : when plate A is turned by 75 degrees it is completely identical to the plate B in length, width and form.

This is an artistic illusion and it is the design of the work which mislead us.

Moreover, the perspective makes us think that the two tables are different.
