Although no book/theories/processes can save anyone's design soul, seeing/understanding Stefan's work has helped me understand that all elements humor/angst/beauty/finesse/distress/ugliness/cynicism can be mashed into this design work we do and can be done without all of this pontification.
This isn't any sort of epiphany, it's just a reaction to all the pretty, high-style fashion driven stuff with no heart/no sense of self that has been floating around for some time.
From most of what I've read, humorous yet always self aware, I feel the connection of rock-n-roll/punk ethics expressed more than just see it. I think this example of pure self expression gives reason for anyone to continue to do this type of work.
