fill(#fee445);
noStroke();

I have these code for the rectangles.
Please help me to animate the rectangles, in changing size. Or may be moving from their origin.

Hi and welcome

Moving it

int x = 0;

void setup() {
  size(640, 320);
}

void draw() {
  background(0, 255, 0);


  fill(0, 0, 255);
  rect(x, 120, 50, 50);


  x = x + 1;
}

Why you are using this loop??

Idea to change size use if or whatever you want to animates it

int x = 0;

void setup() {
  size(640, 320);
}

void draw() {
  background(0, 255, 0);
  fill(0, 0, 255);
  rect(120, 120, x, x);
  x = x + 1;
}

this for loop is to create many rectangles. Actually I want to apply the effect to all the rectangles on the canvas. So please can you help with it.
