The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

Psychogeography A Definition by Guy Debord en.wikipedia.org Psychogeography is an exploration of urban environments that emphasizes playfulness and "drifting". It was defined in 1955 by Guy Debord as: "The study of the precise laws and specific effects of the geographical environment, consciously organized or not, on the emotions and behavior of individuals." "A total dissolution of boundaries between art and life." "A whole toy box full of playful, inventive strategies for exploring cities...just about anything that takes pedestrians off their predictable paths and jolts them into a new awareness of the urban landscape."
