"The word "hobo" used to refer to a traveling worker rather than just a homeless person or panhandler. Starting around the early 1900s, these nomads used a system of etched codes to tell other hobos if there was danger nearby or if they could take shelter with a kindly host. That allowed them sneak into certain places without creating a scene or scaring strangers.
Nowadays, non-profit organizations and generous individuals are adopting the system and putting up similar symbols to help the homeless. Paris' Le Carillon projectis placing pictographs on shop signs to let homeless people know what services are available to them, from free telephone calls to food and clean water."
