Serendipitous unblinking

Despite the fact that I'm the owner of two books about knots and keeping trying out various cross-platform geometry visualization software, I still am wowed by this book's title:
The Shoelace Book: A Mathematical Guide to the Best (And Worst) Ways to Lace Your Shoes

But, then again who am I to be surprised; it's only been a few weeks since I bought a book about a topological object The Mobius Strip: Dr. August Mobius's Marvelous Band in Mathematics, Games, Literature, Art, Technology, and Cosmology.

While I'm fascinated by math, it's not my forte. And, in case you're wondering, I discovered this title after entering a similarly authored book QED about the beauty of proofs at Goodreads.com.
