Hi, I’m very new to coding/processing and would love help with simplifying my code so that it can be expanded easily. Right now I have a grid of 9 images that are stacked on top of each other and then “cropped” using the get() feature so that only 1/9th of each image is shown. It works how I want it to, but as you can see I did it in a messy way that is not easily scalable.
For example, you can see that I typed out the individual values for x[i] and y[i], and I also had to type out a new iteration of “get()” each time. I know so much of this is unnecessary but I am having trouble finding exactly what I should do.
Eventually I want this code to be a 30 x 30 grid using 900 images. Any help to make that happen would be SO appreciated, thanks in advance. 
and yes this an art project about lesbians lol.
//MOSAIC TESTING WITH GET, 9 IMAGES, WANT 900 TOTAL.
