We were trying to get a picture of how a single signifier yields multiple signifieds and thus signs, and how a secondary level of signifieds (a tertiary meaning?) creates myth--the sign of which is the icon. It's based on Peirce's model with Saussure's terminology, Barthes' sentiments (of Myth Today), and allows for Eco's caveat of unlimited semiosis (over-interpretation).
This is a thumbnail of the discussion I had to get down before I forgot. I want to work on it more and write it out more fully before I can explain it in depth. Sam can probably do it the justice I can't.
