Black-and-white candy-striped CIRCLES

Not spirals.  If you don't believe me, trace one with your cursor.

I love optical illusions, and have stored about 40 of them in the blog.  When checking to see if I had done this one before (in black-and-white, in 2010), I rediscovered the wonderful illusion that I've reposted below this one.
