An L-system or Lindenmayer system is a parallel rewriting system and a type of formal grammar. An L-system consists of an alphabet of symbols that can be used to make strings, a collection of production rules that expand each symbol into some larger string of symbols, an initial “axiom” string from which to begin construction, and a mechanism for translating the generated strings into geometric structures.

The field describes a space that is not defined by fixed points or measurements but conditions purpose and activity. Throughout history in art, architecture, science and technology perceptions of space were based on mathematical concepts that do not reflect patterns derived from the natural world. The natural world has always produced fluid and organic spatial matrices.
