Back in the day, hobos used to leave pictographic signs alerting other hobos to such things as the presence of police, free food, etc.

Warchalk is an effort to replicate this hobo language for the wireless age. The idea is that the sort of people who wander around cities looking for wireless LANs to connect to will leave chalk markings for others to let them know they've just stumbled across a usable wireless-access point:

Find a node, and leave a chalk symbol for others to find the node with a minimum of all that tiresome netstumbler business.

The site already has a PDF of symbols suitable for printing.
