::BY ITS COVER::

While at Barnes & Noble tonight, I spied a book I really wanted to buy, but a) I didn't know anyone interested in the Tower of Pisa's history, and b) I couldn't justify picking it up for myself. It's called Tilt, and it's bound as a parallelogram. As in, when one opens it, it's a chevron. (Yes, I know -- most books, as rectangles, are technically parallelograms, but this is one does not have sides perpendicular to its base. So there.) Wow. Link.
