When last we parted, thou wert young and fair — How beautiful let fond remembrance say! Alas! since then old Time has stol'n away Nigh forty years, leaving my temples bare: — So hath it perished, like a thing of air, That dream of love and youth: — we now are grey; Yet still remembering youth's enchanted way, Though time has changed my look, and blanched my hair, Though I remember one sad hour with pain, And never thought, long as I yet might live, And parted long, to hear that voice again; — I can a sad, but cordial greeting, give, And for thy welfare breathe as warm a prayer, Lady, as when I loved thee young and fair!
Shall I compare thee to a summer's day? Thou art more lovely and more temperate: Rough winds do shake the darling buds of May, And summer's lease hath all too short a date: Sometime too hot the eye of heaven shines, And often is his gold complexion dimm'd; And every fair from fair sometime declines, By chance, or nature's changing course, untrimm'd; But thy eternal summer shall not fade, Nor lose possession of that fair thou owest; Nor shall Death brag thou wander'st in his shade, When in eternal lines to time thou growest; So long as men can breathe, or eyes can see, So long lives this, and this gives life to thee.

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.
