_Proun_ was El Lissitzky’s word for his constructions, short for “Project for the Affirmation of the New”.

One diagonal, one red circle, a wedge aimed at it, a few bars, some hairlines and a word, every few seconds rebuilt.

## The generator

```javascript title="proun.js"
const axis = random(-0.75, -0.3);            // the one diagonal
const along = (t, off) => [
  cx + cos(axis) * t - sin(axis) * off,
  cy + sin(axis) * t + cos(axis) * off,
];

circle(...along(random(-0.25, 0.25), random(-0.22, 0.22)), random(0.16, 0.26));
for (let i = 0; i < 3; i++) bar(along(random(-0.3, 0.3), (i - 1) * 0.12), axis);
wedge(from, angleTo(circle));               // aimed at the circle, in the other ink
for (let i = 0; i < 6; i++) hairline(random() < 0.75 ? axis : axis + HALF_PI);
word(random(['ПРОУН', 'КЛИН', 'НОВОЕ', 'ЛЕФ', 'СТРОЙ']), axis);
```
