Elements Ambigram

An ambigram is a word or design that retains meaning when viewed from a different direction or perspective. Specifically, a rotational ambigram reads the same when viewed upside down, while a mirror or bilateral ambigram is one that reads the same backward and forward. (From Wikipedia)

This is a rotational ambigram for the four elements: Earth, Air, Fire and Water. Perfect for making into a multi-colour coaster.
