The first example being related to typography reminded me that Jan Tschichold was one of those influential typographers who's book, The Form of the Book, along with Raul Rosarivo's Divina Proporcion Tipographica, re-popularized the "Secret Canon" of medieval incunabula and brought the Golden Ratio to bear on book layout. Unfortunately we've lost a lot of that beautiful layout design but it can still be found in a few places. For a while, MacBook screens very closely approximated the Golden Rectangle.
