Buy a poster!
Place your mouse pointer on the cross in the middle.
Focus and concentrate on your mouse pointer for at least 60 seconds.
Don't move your eyes. Keep staring at the pointer and the cross.
After 60 seconds, click the left mouse button and HOLD it down.
While you hold the button, the colored boxes will disappear
and you will see ghostly images of different colors.
