Let the white moth go by, Because some wandering spirit it may be That loves the kindly earth so close and dear, It cannot break the bonds that keep it here. The day's for us and all the daylight cheer; Twilight's for delicate things more glad than we. Moths have their right as well as birds to fly; Let the white moth go by.
Let the white moth go by: It has a mate whose wings shine silverly Somewhere beneath the moonlight, calling it To join its airy dances, and to knit Two joys in one, for very full must be The little lives that two suns cannot see — Because we love our childhood, you and I, And would not let one delicate memory die, And know our kinship to all lives that are, To every dewdrop and each falling star — Let the white moth go by.
How much are they deceiv'd who vainly strive By jealous fears to keep our flames alive! Love's like a torch, which, if secur'd from blasts, Will faintlier burn, but then it longer lasts Expos'd to storms of jealousy and doubt, The blaze grows greater, but 'tis sooner out.

How this picture is made
What a fractal is
A fractal is a shape that keeps its pattern when you look closer. Coastlines, trees, shells, and weather do this. The large form and the small form are the same kind of thing. A poem can be drawn that way. The shape of the whole comes from the shape of the lines.
Primunia is the name for the source of that order: the pattern under the pattern, already there in a tree, a shell, and a verse.
How the boundary is drawn
The number under the picture is the poem constant. It is read from the build of the lines: their length, how uneven they are, the size of the stanzas, the share of vowels, and the way the lines end. A new word moves the number when it changes that build. The same poem always gives the same number.
Drawn on its own, that number sits in a quiet part of the plane, and most poems would look like the same soft disk. So the number is carried outward along its own direction until it meets the edge of the Mandelbrot set, where the shape turns sharp. The picture is the Julia set of that meeting place.
Each point on the canvas is folded again and again by one small rule. Points that stay near the rule form the dark interior. Points that rush away become the coloured bands. The hue comes from the poem constant, and the brightest bands turn toward gold. Change the length of a line, the stanza, or the vowel share, and both the number and the picture move.
What the branching signifies
Branching draws the poem as a tree. Each turn follows a line, and every smaller branch repeats that pattern. A longer line reaches farther. The letters at the start of a line bend the next turn. A higher share of vowels opens the branches wider.
The trunk takes its colour from the poem constant and warms toward gold at the tips. When the poem has more than one stanza, gold forks leave the trunk. Each fork is a stanza beyond the first, up to three. The tree divides where the poem divides. One stanza remains a single trunk.
