Guy Debord,Psychogeographic

from:  http://imaginarymuseum.org/LPG/Mapsitu1.htm An example of mapping of atmospheric unities of a city on the basis of ideas of the international Lettrist and Situationist movement. The map of Paris has been cut up in different areas that are experienced by some people as distinct unties  (neighbourhoods). The mentally felt distance between these  areas are visualized by spreading out the pieces of the cut up  map. By wandering, letting onself float or drift (dériver is the  French word used) each person can discover his or her own  ambient unities of a specific city. The red arrows indicate the  most frequent used crossings between the islands of the urban archipel (seperated by flows of motorized traffic).
