  * mousedraw

<code java>

// basic drawing app 

void setup () {
  background(0); // set background color to black
  size (400, 400); // set background size to 400 by 400 pixels
  strokeWeight(3); // set stroke weight to 3
  stroke(255);
}

void draw() {
  if (mousePressed == true) 
    line (pmouseX, pmouseY, mouseX, mouseY);  // draw a point at mouse location

  // code that prints out the values of mouseX and mouseY to the console.
  println("mouseX: " + mouseX + " , mouseY: " + mouseY);
}

  * keypress

<code java>

void setup() {
  size (200, 200);
  rectMode(CENTER);
  ellipseMode(CENTER);
  //noStroke();
}

void draw() {
  background(168, 234, 233); // why is this in draw()?

  if (keyPressed == true) {
    fill(13, 185, 14);
