Two nonvisual factors provide dissymmetry and prevent the ambigram from existing in a static equilibrium; most of the letters in an ambigram metamorphose into other letters when reversed; and each of those accompanying sentences provides a different idea of the word's meaning.

An ambigram is a word that reads the same right-side-up and upside-down. MOW is a natural ambigram, for instance, but any word can be flipped if the right graphic artist gets his hands on it.

Next, I imagine that Switch 2 causes me every single weekend (and every other spare moment as well) to elect, instead of designing ambigrams or working hard on my book about being a strange loop, to spend hours on end watching professional football games on a huge-screen television and delightedly ogling all the busty babes in the beer ads.
