In Ovid's Metamorphoses, Eoos is one of the chariot draft horses of the sun god Helios; the design studio EOOS founded in Vienna 20 years ago is also a driving force, in the today's globalized world of design. This is verified by more than 130 design awards and an impressive number of patents. EOOS pursues a consistent reduced design language, alternating between archaic and high-tech and entirely free from stylistic affectations. This first and long overdue monograph on EOOS is divided into three parts, and is a source of inspiration, analysis, and documentation. Part one is based on a series of images, which gives insight into the "making of" - into the way in which EOOS approaches the design process. It shows references, links, drawings, research material, and finished products. In part two, EOOS assumes the form of first-person narrator to report on selected designs, backgrounds, and details of their histories. Part three documents in chronological order all the EOOS products that have gone into production, as well as projects and design experiments conceived purely by and for EOOS.
