What WARchalking is

WARchalk is an acrynym for Wireless Access Revolution. Inspired by hobo symbols, the warchalking marks were conceived by a group of friends in June 2002 and publicized by Matt Jones who designed the set of icons.

Once a Wi-Fi node/signal is found, the warchalker draws a special symbol on a nearby object, such as a wall, the pavement, or a lamp post. Those offering Wi-Fi service might also draw such a symbol to advertise the availability of their Wi-Fi location, whether commercial or personal. The marks are designed to be recognized by those who understand WARchalk symbols.
