An ambigram is a calligraphic or typographic design with multiple interpretations as written words. Alternative meanings are often yielded when the design is transformed or the observer moves, but they can also result from a shift in mental perspective. This animation shows a half-turn ambigram of the word ambigram. The word is written calligraphically with 180-degree rotational symmetry, such that it reads identically when viewed upside down.Calligraphy and animation credit: Basile Morin
