What do I tink I'll find

I think optical illusions confuse the mind because of the eyes. What I think is that are eyes are moving ,tilting ,plus are vision of color scrambled. So when you look at an illusion it is not really moving are turning a different color, it is just messing with your mind.

I think illusons can be made shapes ,colors ,and patterns arranged to make you think of something else.

I believe that it you can add depth and perspective you can trick the mind even more. An example would be these circles placed on top of each other

I believe if you add depth and color you can make a better illusion, it will look more real.

The drawling above is not a true sprial, it is a series of circles, each one gets smaller than the one it is inside of.
