 Optical Illusion.....WOW! (try it!)
You will see a circle of violet dots. Each of them disappears in order, like moving in a circle.
Concentrate your sight at the black cross in the middle, then you can see, how the violet dots disappear. If you do all right, you can see that the green dot is moving.
If you keep looking, all violet dots will disappear and only the green dot will keep moving!
This is amazing....give it about 30 seconds and be sure to keep focused on the black + sign in the middle! |
