An incredible article from 1977 in which Richard Minsky and his assistant, Peter Seidler, detail the process of making one of the most well known non-codex book structures, Buckminster Fuller's Tetrascroll. I am drawn to the elaborate descriptions of the process from initial prototypes and material testing to the final piece, finished the day it was to be shown (!) at MOMA. It also reminds me (fondly) of the work that occurs at Daniel Kelm's studio in Easthampton, MA, where I worked for two years--new structures, new materials, contemporary books.
