A week or so ago, I posted here some of my ambigrams, including a "through the looking glass" inversion of the name "Lewis Carroll." I did not consider my Carroll inversion successful, and invited readers to do better.
Well, the inimitable and always ingenious Douglas Hofstadter has responded to the challenge. His ambigram is a right-left reflection, which accurately represents Alice's journey, and also takes advantage of the central symmetry of both "Lewis" and "Carroll."
Most readers will know Hofstadter from his hugely popular Godel, Escher, Bach. My favorite of his books is Le Ton beau de Marot: In Praise of the Music of Language.
