深深呼吸一口，那微风的凉润里，分明裹着一丝丝的甜暖，像是新翻的泥土，又像是从枯寂中沁出的缕缕草腥。这气息钻进鼻孔，并不急着往肺里去，倒先在喉咙里打个转，把那淤积了一冬的药罐子似的苦涩，悄然化开了许多。只觉得五脏六腑里那些被寒气淤塞的角落，此刻都被这无形且温柔的手，轻轻地疏通了、抚平了。心头那点莫名的怅惘，也像一块方糖，被这风慢慢地耐心地摇着，化在了一杯清冽的泉水里。

A notable resource on the topic of ordered dithering using arbitrary palettes is Joel Yliluoma’s Arbitrary-Palette Positional Dithering Algorithm. One key difference of Yliluoma’s approach is in the use of error metrics beyond the minimisation of . Yliluoma notes that the perceptual or psychovisual quality of the dither must be taken into account in addition to its mathematical accuracy. This is determined by use of some cost function which considers the relationship between a set of candidate colours. The number of candidates, the particular cost function, and the thoroughness of the selection process itself give rise to a number of possible implementations, each offering varying degrees of quality and time complexity.
A method is described for the manufacture of pivoting colloidal assemblies comprising rotating diamond and rotating triangle geometries that show tunable folding and unfolding by thermal fluctuations and actuation by magnetic attractions.
