Spatial formations are given preference in functioning as structural models - interfaces - for networked text constellations, as they allow for asynchronous networks of different materials, media and processes of action: maps, such as the (imaginary) map of a city, for instance, or a house in the classical art of memory (as sites of cultural memory storage), may also be found in literature in a multitude of ways. There is James Joyce, for example, projecting the ordinary day of June 16, 1904 onto a city map of Dublin, or the cross-section of a Parisian residential building[12], which serves as a homepage for a novel, in which the technique of mise en abyme - in conjunction with multifaceted catalogizations and index lists - enables topographical reading.
[12] In Georges Perec: Life. A User's Manual (originally published in Paris 1978), a branching novel is distributed throughout the rooms of an apartment house: 99 chapters (one for each room of the house, including the cellar rooms, the staircase, the entry hall, and the porter's lodge), which may be crossed through according to the principles of moves on a chessboard. Constitutive elements are developed again and again from the structures of the text-house for each chapter, networking the constellations of persons, furniture, biographical and historical allusions, quotations and literary references with one another. The theme centers around the bizarre story of a puzzle artist in stories that are laid out like a puzzle. This form of a literary game could also be a model for the least "literary" game forms on the Net: the MUDs (Multi-User Dungeons).
