I always thought they were for decorations but...
Has anyone notice those symbols or glyphs that are displayed at the end of each act, just before commercial breaks in the TV show, Fringe? Apparently they are a code that spells a word indicative of that particular episode. In addition to the promotional and marketing value of the symbols, the glyphs are occasionally incorporated as background decoration by the art/set designers. Each glyph highlights a natural element, generally with some unnatural amendment that is cleverly integrated into the image.
After some research I've come across someone, Julian Sanchez, that had cracked the code of those mysterious Fringe glyphs. Also, in each glyph there is a dot and the position of the yellow dot indicate a different letter, so Julian used a simple one-to-one, monoalphabetic substitution cypher.
All someone has to do is print out the chart above while watching an episode. Every time a glyph appears, just mark down what letter it represents and by the end of the episode you'll have a single word that relates to a central theme of the episode.
For example, the very first episode the word is OBSERVER.
