Hello,

This topic inspired me!

Something I worked on:

> **Example of random tiling \< Click here to see code!**
>
> ```auto
> // Pixel Manipulation 
> // v1.0.0
> // GLV 2021-05-30
> 
> let img;
> let cap;
> 
> function setup() 
> {
> createCanvas(640, 480); // Set to video size
>   
> img = createGraphics(width, height);
> 
> pixelDensity(1);    
> img.pixelDensity(1);
>   
> cap = createCapture(VIDEO);
> cap.hide(); 
>   
> //d = pixelDensity(); // Future! See references.
> }
> 
> function draw() 
> { 
> cap.loadPixels();
> img.loadPixels();
>   
> tilesX = 10;
> tilesY = 10;
>   
> //samples = map(mouseX, 0, width, 0, 2000);
> samples = 200; 
>   
> for (let i = 0; i<samples; i++)
> {
> x = (random(width))| 1; // Converts to int
> y = int(random(height)); // Converts to int 
>       
> let loc = x + y*cap.width;
