Artist, designer and educator Elif Ayiter presents "The History of Visual Communication" [citrinitas.com], a dedicated website that focuses on the history of the translation of ideas, stories and concepts that are largely textual or word based into a visual format, i.e. Visual Communication.
Structured into 10 sequential chapters, starting from "Rocks and Caves", over "Ideograms" and "The Alphabet", and ending at the era of the "The Computer", the site attempts to give a complete but very brief overview of the history of typography, illustration, illumination, photography, shapes, color and computer graphics imagery. It also contains many images, most of them in high (presentation friendly) resolution.
