It is interesting to note that the patterns, spatial relations and pattern languages discussed above are closely related to:

Patterns in software engineering
(see James O. Coplien's paper "Space: the Final Frontier")

Spatial/temporal relations and

Visual languages theory

This is not a coincidence. Computer scientists may benefit from the study of theories of architecture. Such cross-fertilization may lead to a deeper understanding of patterns, spatial/temporal relations and visual languages.
