Optical illusions

Stare at the four black dots in the center
of the image for 60 seconds. Then quickly close your eyes,
while facing a lamp of a bright window. With your eyes closed,
you will see a white circle with the face of Jesus inside it.


Stare at the negative image of the Queen for about 1 minute
without moving your eyes. Then look at a blank sheet of paper
and you'll see the queen.
Stare at the black lightbulb for at least 30 seconds.

Then immediately stare at a white area on the screen
or at a sheet of paper. You should see a glowing light bulb!
Stare at the black dotAfter a while the gray haze around it will appear to shrink.

Are these lines straight?

An island, right?

Turn it upside down, and you'll see
what it really is: a crater.

Are the purple lines straight or do they bend?

Pacman Illusion
This is a fantastic illusion ! Stare at the cross in the center and you will see a series of events :

* A circle of purple spots, one spot disappears clockwise.
* A circle of purple spots, one spot turns green clockwise.
* THE GREEN SPOT EATS THE PURPLE ONES !.
* Only the green spot remains, circling around the cross.

Phantom Dots
A very powerful illusion ! You will clearly see gray dots on the corners of the squares. This is actually called the Hermann Grid but let's face it, phantom dots sounds way cooler
