If your eyes follow the movement of the rotating pink dot,
you
will
only see one color, pink.
If you stare at the the black + in the center, the moving
dot
turns
to green.
Now, concentrate on the black + in the center of the
picture.
After
a short period of time, all the pink dots will slowly
disappear,
and
you will only see a green dot rotating.
we dont always see what we think we see
