In many historic examples of font attributes used in visual representations, fonts are used to differentiate categories of information. In the late 19th century writers began to experiment more with typography and layout. In the early 20th century Futurist poet Filippo Tommaso Marinetti encoded the sound and sense of the word with typographic attributes such as italics for quick impressions, bold for violent noises, etc.:
Other examples follow, including beautiful examples adding illustration into the mix as well, such as Le Bestiaire Fabuleux a result of a process from Jean Lurçat, Patrice de la Tour du Pin, Vairel Edmond, Jules-Dominique Morniroli.
Dynamic layouts and variable type to convey semantic information is now more common, for example flowing animated italics for a Mazda sports car in a commercial or clunking heavy sans in a truck commercial.
