Gysin remembers

One finished poster moves through Collage and Plotter Export. The chapters return to choices already present in this sheet.

720 × 900 · one seed · two inks

canvas → layers → frames → field → red return → words → paper

Canvas style

Three JavaScript strings set the paper, black ink and red ink on screen. They do not create SVG layers or choose physical pens.

canvas first · export structure later

const PAPER = "#f0efe9";
const INK = "#151515";
const RED = "#c0392b";

function draw() {
  background(PAPER); // canvas only
  plot.draw();
}

Two export layers

On screen, stroke gives a mark its colour. In SVG, layer keeps paths together. At the plotter, penMap assigns the pens; their ink and width remain physical.

black layer → pen 1 · red layer → pen 2

  1. 1 black
  2. 2 red
const plot = new GysinPlot({
  seed: 19600319,
  width: 720,
  height: 900,
  style: { stroke: INK },
  export: { layer: "black" }
});

const penMap = { black: 1, red: 2 };

plot.circle(256, 337, 450, {
  stroke: RED,
  layer: "red"
});

Hold the page

Three open rectangles hold the page before the words enter it. The first begins above the canvas; only fray and dropout depart from the defaults.

rect() · three unequal fields

plot.rect(80, -70, 544, 170, {
  fray: 0.3,
  dropout: 0.14
});

plot.rect(80, 90, 544, 260, {
  fray: 0.3,
  dropout: 0.14
});

plot.rect(80, 500, 544, 360, {
  fray: 0.3,
  dropout: 0.14
});

Rule the lower field

A loop rules the lower frame with twelve evenly spaced lines. They stay in the black layer and act as measure and rhythm, not ornament.

line() · twelve repetitions

for (let i = 1; i < 13; i += 1) {
  const y = 570 + i * 12.3;
  plot.line(82, y, 632, y, {
    dropout: 0.21,
    rubout: 0.189
  });
}

Build the machine field

Six punctuation marks gather into one bounded field. symbols() repeats them as a clustered machine texture.

/ " ( ) - :

plot.symbols(70, 474, 580, 286, {
  set: '/"()-:',
  size: 20,
  alpha: 0.58,
  cluster: true,
  dropout: 0.2175
});

The red return

A circle crosses the middle field three times. It is the first red gesture and leaves through pen 2; alpha softens only the preview.

red layer → pen 2

plot.circle(256, 337, 450, {
  stroke: RED,
  layer: "red",
  repeat: 3,
  rubout: 0.2,
  alpha: 0.7
});

Four hand gestures

One asemic gesture returns four times along the lower edge. Only its horizontal position changes.

red layer → pen 2

for (let i = 0; i < 4; i += 1) {
  plot.asemic(160 * i, 690, 150, 210, {
    stroke: RED,
    layer: "red",
    breathe: 1.4
  });
}

The typed voices

Seven short phrases remain readable while wear, bold and underline alter their delivery. Observe and REMEMBERS enter the red layer; every phrase remains visible in the complete composition.

underwood() · black and red

plot.underwood("Brion Gysin", 70, 88);
plot.underwood("Continue", 60, 260, {
  bold: true
});
plot.underwood("the small voice.", 60, 190);

plot.underwood("REMEMBERS", 82, 360, {
  size: 50,
  stroke: RED,
  layer: "red",
  bold: true,
  wear: 2.1,
  strokeWeight: 1.4
});

Complete poster composition

Write three times

The same word appears three times: first calm, then breathing, finally marked by dropout and rubout. Each call states only what changes.

text() · readable first, disturbed last

plot.text("write", 60, 220, {
  size: 64,
  breathe: 0.4
});
plot.text("write", 60, 360, {
  size: 64,
  breathe: 1.4,
  dropout: 0.08
});
plot.text("write", 60, 420, {
  size: 64,
  breathe: 2.2,
  dropout: 0.2,
  rubout: 0.2
});

Choose paper at export

page: "A4" chooses a physical export preset. A5, A4, A3 and A2 change the SVG paper, margin and fit without moving the 720 × 900 composition.

exact ISO dimensions · 10 mm margin · clipping · width fit

A4 210 × 297 mm 10 mm margin
plot.downloadPlotterSVG("poster.svg", {
  page: "A4",
  penMap: { black: 1, red: 2 }
});

Take it to paper

Nothing new is drawn here. The same poster leaves the screen as two numbered pen layers; the pens themselves determine colour and width on paper.

Inkscape · layer 1 black · layer 2 red
