1.先畫出視窗，繪畫出會動的眼睛

void setup(){
  size(120,100);
}
void draw(){
  float t=frameCount/180.0*PI;
  background(0);
  fill(255);
  ellipse(40,50,33,33);
  ellipse(120-40,50,33,33);
  fill(0);
  ellipse(40+15*cos(t),50+15*sin(t),5,5);
  ellipse(120-40+15*cos(t),50+15*sin(t),5,5);
}

2.鬥雞眼

void setup(){
  size(120,100);
}
void draw(){
  //float t=frameCount/180.0*PI;
  background(0);
  fill(255);
  ellipse(40,50,33,33);
  ellipse(120-40,50,33,33);
  fill(0);
  float t=atan2(mouseY-50,mouseX-45);
  ellipse(40+15*cos(t),50+15*sin(t),5,5);
  t=atan2(mouseY-50,mouseX-(120-4));
  ellipse(120-40+15*cos(t),50+15*sin(t),5,5);
}

3.雙螺旋

void setup(){
  size(600,600);
}
void draw(){
  background(255);
  float t=frameCount/100.0;
  for(float f=0;f<PI;f+=0.1){
    rect(200+150*cos(f+t),f*100,30,30);
    rect(200+150*cos(f+t+PI),f*100,30,30);
  }
}
