Warchalking now has its own website: Warchalking.org. Warchalking is one of those brilliant ideas that quickly takes the ’net (or at least parts of it) by storm. The basic idea is a set of symbols which can be chalked on walls in areas with a wireless network node to alert other geeks to the availability of bandwidth. I’d go in to it further but the site has as much information as anyone could possibly want on the subject.
