Costumes: the Wearable Dialog • Indistinguishable From Magic
What kind of "stuff" exactly? The kind of articles, commentaries, and interviews where writers and illustrators and directors talk about how they tell a story.
And not the broad kind of "I'm trying to retell Canterbury Tales in Space" type of telling, but rather the specific techniques in a scene or character design that convey unspoken information. All the un-articulated yet still important background information about persons and settings as hinted, suggested, or implied through clothing, through camera shots, or point-of-view narration in text.
