Fading stars

In an attempt I have tried to create something that I thought might be useful at a later date. I have created a a simple version of a night time sky with stars fading in and out.

You can see the code below


void setup(){
size(1000,1000);
background(0);
noStroke();
//this means the ellipses have no outline
}

void draw(){
fill(0,30);
// the first number is the colour the second is the opacity
rect(0,0,width, height);
//this rectangle covers the whole screen
fill(255);
ellipse( random (width), random (height), 3, 3);
}

then I used

if (mousePressed){
saveFrame(“line-######.jpg”);
}

to save several images.

I then combined them in terminal using this code  convert -delay 20 -loop 0 *.jpg result.gif.

and here is the end result.result
