In this book, Carsten Nicolai explores the moirea effect—a phenomenonthat can be created by the overlay of lines. Although such interferencepatterns are mostly considered to be unwanted side effects, they areactually extremely interesting from an aesthetic perspective. This firstextensive visual compendium of these patterns is accompanied by a CD thatcontains not only the featured moireas as digital files, but also individualelements that can be used to create an almost endless amount of newoverlays. By analyzing and systematically unlocking these fundamentalstructures of crucial importance to the visualization of data, Nicolai hasagain produced not only a work of art, but also a practical tool for anyoneworking creatively.
