Optical Illusions

One of the 4th grade student here showed me a bunch of optical illusions from her book.

These are very interesting -- they are all amazing...

Be sure to observe #7 as instructed..this one is special!!

1)

Is this possible?

2)

Are the purple lines straight or bent?

3)

Do you see gray areas in between the squares?

4)

You should see a man's face and also a word...

Hint: Try tilting your head to the right, the word begins with 'L'

5)

If you take a look at the above picture, let me tell you...It is not animated. Your eyes are making it move. To test this, stare at one spot for a couple seconds and everything will stop moving. Or look at the black center of each circl e and it will stop moving. But move your eyes to the next black center and the previous will move after you take your eyes away from it...Weird ?

7)

This is without a doubt, one of the coolest PC- Illussion, I have seen so far.
Follow the instructions:

1) Relax and concentrate on the 4 small dots in the middle of the picture for about 30-40 secs

2) Then take a look at a wall near you (any smooth single colored surface)

3) YOu will see a circle of light developing.

4) Start blinking your eyes a couple of times and you will see a figure emerging....

5) What do you see? Moreover, who do you see?
