Stare at the eye of the red parrot while you
slowly count to 20, then immediately look at one
spot in the empty birdcage. The faint, ghostly
image of a blue-green bird should appear in the
cage. Try the same thing with the green
cardinal, and a faint magenta bird should appear.

If you take a look at the following  picture ,
let me tell you ... it is not animated.  Your
eyes are making it move.  To test this, stare at
one spot for a couple seconds and everything will
stop moving.  Or look at the black center of each
circle and it will stop moving.  But move your
eyes to the next black center and the previous
will move after you take your eyes away from
it....  Weird

1) The Pepsi Cool Can In 1990, Pepsi actually
withdrew one of its Cool Can designs after
someone protested that Pepsi was subliminally
manipulating people by designing the cans such
that when six-packs were stacked at grocery
stores, the word SEX would emerge from the
seemingly random design. Critics alleged that the
red and blue lines on the Cool Can design were
far from random.
