つぶやきProcessing

This animation is a p5.js example sketch borrowed from an article on つぶやきProcessing by Koma Tebe (You can read about it here.) I used it to learn more about p5js, つぶやきProcessing, and web graphics.
In order to embed this p5js sketch in an X tweet, I first reworked it so it would run in the Processing IDE, exported it as an mp4, then converted mp4 to GIF with ffmpeg, using the command: ffmpeg -i xxxx.mp4 xxxx.gif. Simple enough.
Note that "createCanvas" and "let" are not keywords in Processing. You need to change "createCanvas()" to "size()," and "let" to "float" (so that index "i" is declared as a float).
