Another parametric functions. Inspired from <a href="/plots/111">plot#111</a> idea: stacking multiple parametric functions. The parametric used is
<pre><code class="language-rust">let parametric = |t, p| {
 (
 (0.2 + 0.7 * p) * (2. * PI * t).sin()
 + 0.1 * (14. * PI * t).sin(),
 (0.2 + 0.8 * p) * (2. * PI * t).cos()
 + 0.2 * (20. * PI * t).cos(),
 )
};

Another parametric functions. Inspired from <a href="/plots/111">plot#111</a> idea: stacking multiple parametric functions. The formula is <code>(0.3+0.7p)f(2πt)+0.05f(8πt)</code> where p is the growing factor, t is the parametric value and f is a cos for x and sin for y.

There is an increase amount of perlin noise and a subtle use of two different ink tones: &quot;Pink Glitz&quot; and &quot;Red Dragoon&quot; by Diamine. Fountain pens on A4 bristol card.
