This is my 30 years belated realization that PHIGS was a 'graphics' pun pretending to be an acronym. I'm not sure if that makes me hate it more or less. I'm leaning towards more. The focus on PHIGS was less welcome when I read Foley and Van Dam than the chapter on dot-matrix printing which at least had some timeless "how stuff worked" appeal. Teaching specific APIs in a textbook almost never ages well.
