This will drive you nuts! Make sure you read under the
illusion, too....
This is another example of an amazing illusion!!! The last sentence is so true.
If your eyes follow the movement of the rotating pink dot, you will only see
one color, pink.
However if you stare at the black "+" in the center,
the moving dot turns to green.

Now, concentrate real hard on the black "+" in the center of the picture.
After a short period, all the pink dots will slowly disappear, and you will only
see a green dot rotating.

It's amazing how our brain works. There really is no green dot, and the pink
ones really don't disappear. This should be proof enough, we might not

always
see what we think we see.  
If you are up to the great illusion
here is the door to an unusual
journey.

THE ILLUSION OF REALITY 58:58 - 2 years ago
In the last in the series Professor Jim Al-Khalili explores
how studying the atom forced us to rethink the nature of
reality itself. He discovers that there might be parallel
universes in which different versions of us exist, finds out
that empty space isn't empty at all, and investigates the
differences in our perception of the world in the universe
and the reality.
