Design Principles

There is a strong evidence that the various areas in the island have been designed around some clear principles or themes, and that these principles affect:
 * the design of the puzzles (notably, the design of the rules associated to some symbols),
 * the architectural features and usage of the place,
 * the patterns of navigation in that place,
 * the environmental puzzles, perspective tricks and audio logs in that place.

= Identifying the Design Principles = These design principles are sometime obvious. For instance, the Symmetry Island area has been designed around the concept of symmetry. On the other hand, identifying these principles is sometime complex and requires to pay close attention to small details and to explicitly search for such principles. Even when the principles seem obvious, such attention is required to understand the full extent of the use of the principles and variants in the realizations of these principles. Identifying the design principles can therefore be considered as a high-level kind of puzzle, which uses different types of clues (an important one being the white flowers).
