F for Fibonacci takes as its departure point American author William Gaddis' epic novel JR from 1975. A biting social satire, the book tells the story of a precocious teenager capitalist who, with the unwitting help of his school's resident composer, inadvertently creates the single greatest virtual empire the world has seen. In F for Fibonacci, musings on aleatory music become muddled with financial abstraction and a theory of "market noise". As well as the writing of Gaddis, the film draws on the work of little-known British experimental educator and composer John Paynter. Beatrice Gibson worked closely with 11 year old Clay Barnard Chodzko on a number of the film's elements, commissioning him to design an office in the computer game Minecraft and develop an existing character of his, Mr Money. Gibson and Chodzko's ramblings on the subject of his protagonist lead the viewer through the film's hallucinatory soup.
