The glow of grime Of course this 'sheen of antiquity' of which we hear so much is in fact the glow of grime. In both Chinese and Japanese the words denoting this glow describe a polish that comes of being touched over and over again, a sheen produced by the oils that naturally permeate an object over long years of handling—which is to say grime. If indeed 'elegance is frigid', it can as well be described as filthy. Jun'ichirō Tanizaki & Thomas J. Harper, In Praise of Shadows timeaestheticsfilthflaws
The scale of resolution determines what is seen The patterns of Truchet's tiles appear at first glance as variously shaped interlocked regions of black and white, the boundaries between the square tiles being submerged whenever the two regions flanking them have the same color, just as in a real floor the air or cement between the tile edges is not perceived—until one looks closely. The scale of resolution determines what is seen. Cyril Stanley Smith, The Tiling Patterns of Sebastien Truchet and the Topology of Structural Hierarchy Levels of Scale patternsscale
