The same author has a great series of tutorials for making looping animations, where the animation appears longer than the length of the loop. It also introduces Perlin noise, which I've found quite useful in a few unrelated projects.

Here is an example of a 10-minute movie in a 6.3-second looping GIF. https://bsky.app/profile/johsenevoldsen.bsky.social/post/3lmca7h3rgs2h

The same artist has some excellent tutorials on how to implement a lot of those effects: https://bleuje.com/tutorials/

Technically you can (licensing though needs to be checked). Just check/inspect the code of the page, look for video tag and see the source url, e.g. [0]
0. https://bleuje.com/mp4set/2021/2021_01.mp4
P.S. You can even check out how author's animations increase in complexity over time by changing year and month manually (or finding the full list of videos in one of the js files). Great work!

They’re pretty amazing.
Looks like it it’s processing (not processings JavaScript cousin p5js).
There is a tutorials section where the workflow is discussed. And how to create the infinite style loops.

It’s processing then exported as gif to animated gif.

Are these all done with Processing? Love the first one on this page: https://bleuje.com/animationsite/2021_2/

See https://bleuje.com/animationsite/2024_1/ for a collection of programmatic black and white animations made with https://processing.org/
He publishes the source code on https://github.com/Bleuje/processing-animations-code/tree/main

The author's archive of animations is very pleasing: https://bleuje.com/animationsite/2024_1/

Check out this guy's work: https://bleuje.com/animationsite/2023_1/

He publishes a couple with the source code: https://github.com/Bleuje/processing-animations-code
Also he published some full tutorials that are more conceptual, which you can find here: https://bleuje.com/tutorials/
I found the tutorials had a lot of awesome ideas (like traversing 4d noise for a seamless loop!) which I ended up playing with in my own projects. I don't use processing like he does, but all the tutorials are very easy to understand even if that's not your tool of choice.

You can see a list of them, in chronological order, from the main site — click 'latest animations'[1]

The site actually has some tutorials for creating these sorts of animations with a specific focus on perfectly looping gifs [1]. Looks like it's all done with Processing [2].

What makes Processing useful for such visualizations? Haven't really looked at it, but the tutorial here [1] begins with rendering images and then combining them into a gif, which seems a bit awkward?
