Optical Illusion

< Eyes, lie, illusions > is a great and intriguing book, it arose my interesting for optical illusion,
which relate to such broad areas beyond my anticipation.
Now I understood the reason that Pete always lead me to explore it.

Just at the beginning of the book, i got lots of useful key words,

which quite worth to think about it.

And also, i researched some other data form world book.

I choose four famous pictures about optical illusion.

( Unfortunatly, i don't know why the quality of pixs always be bad when i post on blogger....-.- But i can see it so clear was saved from PS. Maybe is cause the blogger compress it automatic. )

Well..

Recently, i'm reseach two sorts of optical reactions made of after image:

Illusion and delusion (hallucination? i'm not sure how to call it more accurate ),

they are similar but different.

I want to display the delicate difference between illusion and delusion through After Image.

How does influence for a space could be.

It is necessary to research the different intention of Illusion and delusion in existent works,

such as some architectures and installation art.

And also, optical illusion that refers to an image continuing to appear in one's vision after the

exposure to the original image has ceased.

In the spatial restrictive field, what condition should be use corresponding between

Illusion and delusion?

To me, the trend of delusion is erratic, abstract and perceptual, as a dream,

while the Illusion is like a magic, odd outside but rational and well-founded inside.
