Two sweet math books of 2009

A couple sweet math books for a broad audience (and, coincidentally, the last two additions to my collection) include:
Logicomix, a graphic novel about Bertrand Russell's quest for certainty in the foundations of math, and the madness that mysteriously infuses the study of logic.
The Math Book, a survey of important ideas in mathematics throughout history, distilled into 1-page summaries with full-color graphics.
