If modern design moved the stage picture away from the specific, tangible, illusionistic world of Romanticism and Realism into a generalized, theatrical, and poetic realm in which the pictorial image functioned as an extension of the playwright's themes and structures (a metanarrative), then postmodern design is a dissonant reminder that no single point of view can predominate, even within a single image.
