Optical Illusions

I want to introduce some fun optical illusions !


All the squares seem to line in one big spiral.
But if you look at this picture closer, you can see there are many circles with squares and
they are not connected to each other.

This is just a painting not a moving image.
But it somehow seems like moving.

This is also a painting which looks like there is a wace on the picture.

But actually it's not moving.

The white dots between the squares blink black and white.

But it's optical illusion.
