This is one of the most fantastic optical illusions I have ever seen! 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!
Its seems that this illusions does not always work in the same way. Sometimes pacman eats every purple dot in sequence, sometimes he eats them completely at random. What do you see?
This illusion is also known as the Lilac Chaser.
