... The Fractal Geometry of a Poem. (Hat tip, Dave Lull.) I think it interesting that "perfectly symmetrical verse forms have never gained much traction in English." I am reminded of a point Isak Dinesen makes in Shadows on the Grass, that true unity demades a degree of dissimilarity, that two left hand gloves are worthless. It is a left-hand glove and a right-hand glove that constitute a unity.
