      abstract = {An introduction to maritime communication through nautical  flags, along with morse code, the phonetic alphabet, and  semaphore signaling. Today's system of international  maritime signal flags was developed in the 19th century,  and is still used for communication between ships, or  between ship and shore. Each flag, boldly colored for  visual distinction at sea, stands for a letter as well as a  phrase relevant to seafaring. The resulting code is both  beautiful and functional, inviting readers to code and  decode messages of their own! --},
