Typography nerds are some of my favourite nerds.

Font specimen pages are so often screaming with design language and intention, they push and prod to evoke and present.

Andrew Glassner's Notebook: Recreational Computer Graphics is a really neat book (I especially like the tiles that can add numbers). The author's site is https://glassner.com/computer-graphics/

Chapter 6 in the book ( https://archive.org/details/andrewglassnersn0000glas/page/98... ) Signs of Significance starts with 7 segment displays to the 14 segment and 5x7...
