I love looking through these examples by the old masters; I wouldn't say you can feel the person who was writing, but you can feel the energy with which the writing was done. Some writings are Correct and authoritative; some are somber or subdued; many are playful or energetic; some are made to look like something else. There's an expressiveness to kanji that English, love it though I do, doesn't afford.
The kanji in question isn't iki; it's one I found along the way. Not surprisingly, it's 愚 (gu), foolishness—in this expression, a foolishness which literally surpasseth the margins. I enjoy its lightness, indifference, dancingness. I loved writing yama in gyousho for the same reason: It always seemed to be running. (行、走)
I'd better write 愚, too, for around the house. Or maybe have it tattooed onto my face.
