Description: On the history and creation of ambigrams, by a pioneer of the practice
Review Quotes: "Hofstadter [has] poured his inexhaustible love of tricky form into doodles he calls 'ambigrams.' . . . The product of tweaking and iteration, . . . they are often charming."--Wall Street Journal
"Spellbinding and truly one-of-a-kind. . . . Written in a disarming, conversational tone that belies Hofstadter's mastery of the subject matter, and lavishly illustrated with full-color diagrams on nearly every page, this is an absolute delight."--Publishers Weekly (starred review) "A unique book."--Microsiervos
