In Praise of Shadows by Jun'ichirō Tanizaki

"A Japanese room might be likened to an inkwash painting, the paper-paneled shoji being the expanse where the ink is the thinnest, and the alcove where it is darkest. Whenever I see the alcove of a tastefully built Japanese room, I marvel at our comprehension of the secrets of shadows, our sensitive use of shadow and light."
