Changing Size of Object Slowly

How would you go about changing the size of an object when you click the page. I realize there are many ways to do this but I specifically want the shapes to gradually increase/decrease given an array of numbers.

    In what way would the array affect the size? Would the array be a series of sizes to change to?

    As you said there are many ways to do this. Below is the simplest example I can think of, a circle either grows or shrinks to some target size at a constant rate:

    int current, target;

void setup() {
  size(400, 400);

  // Target size is half the width
  target = width/2;

  // Start from a random size
  current = (int)random(width);
}

void draw() {
  background(255);
  ellipse(width/2, height/2, current, current);

  if (current < target) current++;
  else if (current > target) current--;
}

void mousePressed() {
  // Do it again if the mouse is pressed
  current = (int)random(width);
}
