Stefan Sagmeister

"Long ago, Sagmeister, whose motto was “Style=Fart,” replaced style with attitude. His designs are rooted in disorienting images and self-defining aphorisms. With apparent ease, Sagmeister morphs—as tricksters are wont to do—taking on various skins, from graphic designer to conceptual typographer to performance artist. When the mood strikes, he returns to being a designer, and a completely new cycle of transformation commences."
