The latest instalment in the renowned "Pamphlet Architecture series" features the technologically progressive young firm Aranda/Lasch, illustrating their use of advanced computational methods and algorithmic code in architectural design. Tooling is broken down into seven sections: blending, cracking, flocking, losing, packing, spiralling, and weaving, each corresponding to a pattern generated by computer codes, which in turn creates an organizational template for putting projects together - from building materials to large-scale populations. Each section is broken down through a simple recipe that describes the organizational template; sketches and geometric diagrams of that recipe; an architectural project that utilizes the algorithms; and finally the computer code of the various algorithms created for the book.
