The mosaic pattern was developed to be a "fifth element" on the design of this e-book. A recognizable pattern. In the following book series the same pattern will be used to link the books together, but with a different color background. The main display font are characters from the Greek alphabet, modified into legible letters. As the writer has strong influences from Greek history and science. He wanted this to come through on the design, along with the symbols for sigma, phi and pi.
