Also, check out Le Cent Quatre, in which they discuss about their process and how they eventually quit the project. (below)

A large role in our design philosophy, and thus also
in the graphic language we developed for 104, is the
idea of the design-as-an-object, as opposed to the
design-as-an-image. What we mean is this: when
we are designing, we never think of the image on our
computer-screen as the finished product. For us, the
design is finished, only when it is printed on an actual
object, and not earlier.
Often, a design that looks still quite minimal and dry
on the computer-screen, suddenly begins to live the
moment that it is printed on a shirt, a bag, or a piece
of paper.
