Illusions

Here are a few illusions I thought you might enjoy. The first one is my favourite, but the rest aren't in order. Read the instructions below the images before you start.
Here you go:


Concentrate on the little dots on the middle of the picture for about 30 seconds. Then, stare at a white (or blank) wall and blink repeatedly. Who is it?


How many faces can you see? (Hint: there are more than 40)


How many pandas are there?



Concentrate on the little dots on the middle of the picture for about 30 seconds. Then, stare at a white (or blank) wall and blink repeatedly. Who is it?


Which middle circle is the biggest, right or left? (Answer: they are exactly the same size. to prove it, take a ruler and measure.)


Stare at the + in the middle of the circle for about a minute. Try to SELDOM blink. You'll see what happens to the magenta dots.



Move your eyes across the image and see the picture move.
