Ambigram
By Ryan Grohsmeyer
"Recently I read a book about ambigrams, which are words or phrases that can be read both downside up and upside down. It made sense that the name of the book, which is such an important representation of the relationship between earth and sea, could be easily made into one of these ambigrams. This picture has no bottom or top; it can be mounted and read either way. When it is turned, Earth becomes Sea and Sea becomes Earth."— Ryan Grohsmeyer
