Seems like everyone is talking about Headmap. It’s a pretty cool project, compiling research on how “location aware devices” can be used for social change. There’s a lot of information on this site, but I have a hard time reading the tiny, light grey font and the lack of text formatting makes the material hard to scan. Still, they’re doing well to compile large amounts of theory regarding place, magick, and technology. They’ve built a prototype of what they’re talking about, but it’s still very rough. So far it’s basically a map with links to web pages that deal with the places on the map. I think Hiptop Nation is more interesting right now, and it isn’t even trying to be any sort of revolutionary psychogeography tool.
Update: The Headmap site is gone, but I’ve preserved the Headmap Manifesto here
