See [New to class and need a project - #2 by Chrisir](https://discourse.processing.org/t/new-to-class-and-need-a-project/34972/2)

Let’s say you work with a for loop to display c images

c is the upperBound of the for loop - check out the reference

c= map(mouseY, height, 0, 1, 128);

or whatever - see reference for map()

for the positions use an array with PVector and fill it in setup ()

So before setup():

PVector[] list = new PVector[128];

fill it with random positions in setup

(a random throughout would make the images jump and everything would flicker)

(lots of room for improvement, eg. size, rotation, relocation…)
