Some people may react to this anomalous motion optical illusion and if you think you might be one of these people it is important to read the caution at the top of this page prior to proceeding.
Below is an optical illusion by Miwa Miwa that actually has four separate illusions in it. Can you spot the 4 different illusions? If you have trouble check the bottom of this post for an explanation of the four illusions.
Thanks Miwa for sharing your illusions with us.

Miwa said the following about this illusion:
This work was published in Mainichi Shimbun (newspaper)on the New Year's Day of 2006. It is original for the page "World of the optical illusion". It is an illustration including four kinds of optical illusions.Two of the illusions are anomalous motion, the sky and the green jacket. The sky is also an example of the Spiral illusion, do you see a spiral or is it really multiple concentric circles? The dogs Jacket is the fourth illusion and an example of the Scintillating Grid optical illusion. Look close, how many black spots do you see?
