We watched Helvetica today in History of Design. Helvetica may or may not be the typeface of the Establishment. It may or may not be responsible for the Vietnam war. It may or may not be socialist. It is definitely a darn entertaining documentary, even if you're not a type geek.
Erik Spiekermann is one of my new favorite people. (The interview begins around the two minute mark, and really you should just go watch the movie.)
More Erik Spiekermann being awesome.
