// No for loop here. Instead, a global variable.
int y = 0;
void setup() {
size(200,200);
background(255);
// Slowing down the frame rate so we can easily see the effect.
frameRate(5);
}
void draw() {
// Draw a line
stroke(0);
// Only one line is drawn each time through draw().
line(0,y,width,y);
// Increment y
y += 10;
// Reset y back to 0 when it gets to the bottom of window
if (y > height) {
