I first read the headmap manifesto back in 2002, and I have picked it up a few times since. I think its an important part of dwelling in digital and would like to offer it here, its an incredible read on location based technologies. The Headmap is a look at both the social and technical potential of spatialized computing, where the world’s “real borders, boundaries, and space become plastic and malleable, statehood becomes fragmented, and global.” Here space can be contextually altered with the placing of data, examples are leaving annotations at specific locations for a your own network of contacts to discover, or room that have accessible histories.
