可以断定,这风来自宇宙,来自地球四季轮替的铁律,尽管它悄然而至,却也挟带了无限辽远的信息:那是冰层坼裂的轰鸣,是万千根须在黑暗中摸索的窸窣,是无数生命在挣脱与拥抱之间那甜蜜的喘息。这春风,哪里仅是地理上的气流?它分明是时间本身最温柔的手,在徐徐推动着生的轮回。它将逝去的冬,酿成滋养新生的腐殖;它将枯寂的枝条,吹成待放的蓓蕾。在这永不停歇的循环中,生老病死的面目似乎并不那么可怖,它成了一个必要的休止符,一次深长的呼吸,一切的一切,无非都是为了下一句更嘹亮的歌唱。

Dithering in its simplest form can be understood by observing what happens when we quantise an image with and without modifying the source by random perturbation. In the examples below, a gradient of 256 grey levels is quantised to just black and white. Note how the dithered gradient is able to simulate a smooth transition from start to end.
