从 G 一直贯穿到 N 的连续木纹，仿佛这五个字母都是沿着同一块木板切割出来的

"continuous wood grain that flows unbroken from the G through the N as if all five letters were cut from one plank" The spelling constraint: "The only text in the image is the word GRAIN and the single small line below it, spelled exactly as written." One word and one texture is the whole poster. Restraint is a setting too.

从 G 一直贯穿到 N 的连续木纹，仿佛这五个字母都是沿着同一块木板切割出来的 拼写约束："图中唯一的文字就是单词 GRAIN 以及其下方唯一的那条小线，拼写与所写完全一致。" 一个词、一种纹理，就是整张海报的全部。克制，本身也是一种设定。
