Ambigrams are word renderings that can be read both right-side up and upside down (or, sometimes, in a mirror). They’re hard to do convincingly, though some designers are pretty good at it. The one above was actually generated by a computer: Word.Net’s Ambigram.Matic. It’s not as elegant as the others, but I’m surprised that a machine can do this at all.
