OVERVIEW: This screen, which looks like an old-fashioned phone dial beside text, functions as a "visual table of Contents" about the presentation and serves as an ideal "Home" screen. By using a series of images, it literally provides a snapshot of the material that will be covered. It is an ideal introductory screen which does not present much content on its own; the content is all made available through links to other screens which allow significantly more quantities and more varied kinds of information to be presented.
