* "In Gravett's gifted hands, an old math problem springs to life--and more life and more life! Medieval mathematician Fibonacci's "rabbit problem," in which bunnies breed at a specified rate, provides the structure of this glorious faux--wall calendar that watches a rabbit community from January to December...Readers needn't care about the math of Fibonacci Numbers to love the hilarious, jam-packed visual details, many of which are playfully metatextual...Endless fun to pore over for kids and math-minded or geeky adults.
