Optical Illusion #6

It has been a while ago since I posted my last Optical Illusion Collection. I don't know why. I guess I just forgot that I was doing it. Anyway, here is another one. It is called "false spiral" -- actually a series of concentric circles, hard as it may be to believe. To prove that there's no spiral, try tracing your finger around one of the circles. You'll see that it never moves inward or outward. Happy viewing!
