In a mass of large bubbles The froth, therefore, though lacking long-range symmetry, nevertheless has very definite rules as to its composition. It is pleasing in appearance because the eye senses this interplay between regularity and irregularity. Structure, Substructure, and Superstructure symmetry
We wonder which is real, he of the picture or he who talks? In the tea room the fear of repetition is a constant presence. The various objects for the decoration of a room should be so selected that no color or design shall be repeated. If you have a living flower, a painting of flowers is not allowable. If you are using a round kettle, the water pitcher should be angular. A cup with a black glaze should not be associated with a tea-caddy of black lacquer. In placing a vase or an incense burner on the tokonoma, care should be taken not to put it in the exact center, lest it divide the space into equal halves. The pillar of the tokonoma should be of a different kind of wood from the other pillars, in order to break any suggestion of monotony in the room. Here again the Japanese method of interior decoration differs from that of the Occident, where we see objects arrayed symmetrically on mantelpieces and elsewhere. In Western houses we are often confronted with what appears to us useless reiteration. We find it trying to talk to a man while his full-length portrait stares at us from behind his back. We wonder which is real, he of the picture or he who talks, and feel a curious conviction that one of them must be fraud. Okakura Kakuzō, The Book of Tea repetitionsymmetry
An index of the shifting patterns "Because this is a garden where things can be left out at night without being stolen, we're going to 'furnish' the garden with French café chairs that won't be secured in the ground, so people can move them to wherever they want to sit...It's like with the chairs being totally casual and relaxed and comfortable. They set a tone. There's things that you have to do to get the right feel, where it's all already there, but then, you know, 'Bing!' – there's a moment of recognition." The patterning of chairs pulled together in different ways by successive waves of visitors over the course of the day becomes an index of the shifting patterns of people that sit in a variety of arrangements to facilitate conversations and other intersubjective alignments, or simply to allow for a moment of private contemplation free from contact with others.
