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.
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.

Internet users see URLs both online and in print, and therefore URLs have visual interfaces. This paper gives an overview of many of the issues that concern the visual and user interfaces of URLs.
