The book Lines of Joy documents the oeuvre of Hungarian architect Gábor Farkas. The publication is divided into three main parts, with differently coloured pages for orientation: Farkas’s own writings are printed on a white background, while analyses by his colleagues feature against a red background, and interviews with Farkas use a black background. In addition, the book also has smaller pages with perforated edges, presenting archived materials such as old e-mails, business cards or hand written letters.
