Go see this movie. Rent it. Netflix it. Check it out from the library. Even those who work with type every day will learn so much. What a great documentary.
Helvetica is quality, only seconded by avant guard !!! stunning type faces really neet well designed letters, and unlike those ugily groovy fonts can be used for sooo much things !
comic sans is even worse, come on! helvetica is just a general decision... anyway the movie is great! you really have to see it, if you want to understand modern design
