Black Dots Illusion
How many black dots can you see in this illusion picture? Hard to count it because the black dots and white dots are flashing? Actually, there are no black dots at all. Try to see one dot to one dot slowly, then you will know there is no black dot.
The illusion is known as the scintillating grid, and was discovered by E. Lingelbach in 1994.
