I first started by substituting every 0 for “CIRCLES”.  I used a triangle in the background, centering it and setting the fill color to the same as the background, and setting the strokeWeight to 3 to get the outline. I used a mouse follow code and had circles randomly generated to follow the mouse. The color and the strokeWeight, as well as the Stoke, are all randomly generated; as I could not choose a single color. If you click on the mouse, rectangles will join the circles in following the mouse. The rectangles are also randomly generated with strokeWeight, and the fill color, but the stroke was narrowed down to randomly generate more blue/green tones. My favorite part, by far, is the surprise rectangles.

 

My Code:

int CIRCLES = 0;

void setup() {
size (900, 600);
background(3, 24, 59);
fill( 3, 24, 59);
stroke(CIRCLES);
strokeWeight(3);
triangle(100, 500, 800, 500, 450, 10);
}

void draw() {
stroke(random(CIRCLES, 225), random(CIRCLES, 225), random(CIRCLES, 225));
fill(random(CIRCLES, 225), random(CIRCLES, 255), random(CIRCLES, 255));
ellipse(mouseX, mouseY, random(10), random(10));

if (mousePressed) {
stroke(random(CIRCLES, 41), random(CIRCLES, 225), random(CIRCLES, 80));
strokeWeight( random ( CIRCLES, 10));
fill(random(CIRCLES, 225), random(CIRCLES, 255), random(CIRCLES, 255));
rect(mouseX, mouseY, random( 0, 50), random( 0, 100));
}
}
