Look at the next slide.
Focus on the 4 small dots in the centre of the picture and look at the picture for 30-40
seconds.
Afterwards blink your eyes couple of times to the nearest wall.
What do you see?

The SCINTILLATING GRID – black dots appear at random intersections
Focus on a single intersection, the dot does not appear. The dots disappear if you are too close or too far from the image.

If your eyes follow the movement of the rotating
pink dot, the dots will remain only
one color, pink.
However if you stare at the black " +" in the
center, the moving dots turns to green.
Now, concentrate 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 only a
single green dot rotating.

In black you can read the word GOOD; but the word EVIL also appears in white letters inside each black letter.

What do you see?
You should see a face ….
but also a word.
Tilt your head to the right – the word begins with L.
