@greweb&#39;s #12 plot loop. Taking the idea of <a href="/plots/198">plot#198</a> to the next level using an animated eye.
These are plotted (~ 2 hours each frame) with fountain pens and two inks (&#39;Bloody Brexit&#39; by Diamine and &#39;Writers Blood&#39; by Diamine) on a A4 watercolor paper (300g/m2).
The eye is mirrored with a different offset to make this duality. The title refers to the French expression &quot;œil pour œil, dent pour dent&quot; which means &quot;an eye for an eye&quot;.

I took a video of my wife eye and use this GIF as an input to my generator =)
<video src="/images/plots/202-input.mp4" width="100%" controls autoplay muted loop></video>
The way to mix the two eyes is using a simple technique, using my own tool set:
<pre><code class="language-rust">let get_color_1 = image_gif_get_color(&quot;images/eye.gif&quot;, opts.index).unwrap();
let get_color_2 = image_gif_get_color(&quot;images/eye.gif&quot;, opts.index + 2).unwrap();
let f = |(x, y): (f64, f64)| {
 let p = (x, y);
 let c1 = get_color_1((p.0, p.1 + 0.2));
 let c2 = get_color_2((p.0, 1.2 - p.1));
 smoothstep(0.0, 1.0, grayscale(c1)) *
 smoothstep(0.0, 1.0, grayscale(c2))
};
</code></pre>

Today is 200th day of 2021. I started plotting on January 1 on a daily cycle, so let&#39;s celebrate this 200th plot. I&#39;m using here a very similar technique as explored in <a href="/plots/198">plots#198</a> with even more tight lines and different settings used in combination with a coffee cup photo.
This plot is a tribute to artist Sean M Puckett (<a href="https://twitter.com/PhotoPuck">@PhotoPluck</a> on Twitter), who I consider an incredible artist of the plotting scene. They are frequently releasing impressive photo-driven plots, pushing the boundaries of what can be done with fountain pens. Please check their work on <a href="https://twitter.com/PhotoPuck">https://twitter.com/PhotoPuck</a>.
I like their regular &quot;Monday coffee plot&quot; that I wanted to celebrate.
