Math Teachers at Play Blog Carnival
Alexander Bogomolny is hosting the Math Teachers at Play Blog Carnival 28. I’m very excited, since 28 is my favorite number, and I absolutely love the autostereogram that he created to introduce the carnival:
To see the image, focus your eyes behind the screen. Keep staring for quite a few seconds. Most people have to let their eyes get a little blurry, and it may be mildly uncomfortable — but only for a moment. And it’s worth it! When you are finally able to decouple eye convergence from lens focusing, a three-dimensional image will “pop” off the screen. The result is nothing short of magical.
Thanks to Alexander for hosting the carnival and for providing this cool stereogram!
