German illustrator and designer Christoph Grünberger's (born 1975) Analog Algorithm is a tool kit to create new forms using grid-based design, offering the reader techniques to develop new forms, fonts, logos and patterns. The concept represents a design process in which individual decisions follow much larger and deeper principles than immediate and spontaneous-intuitive actions.Using a variety of examples, each chapter contains a detailed description of the procedure from form analysis to setting up design rules and their application. Both a workbook and a source of inspiration, this publication provides designers and architects with the tools they need to find analytical forms―analog, algorithm-based, exploratory but never of arbitrary origin.The procedures described allows for an almost infinite number of possibilities. The designer is thus transformed from inventor to interpreter or curator, who assesses individual forms for logos, fonts or patterns on the fly and ensures that the design process is always efficient and goal-oriented.
