一.眼珠轉動

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);
}

二.眼珠跟著游標移動

void setup(){
  size(320,300);
}
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-(120-40));
  ellipse(120-40+15*cos(t),50+15*sin(t), 5,5);
}

三.螺旋狀方框

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), 200+150*sin(f), 30,30);
    rect(200+150*cos(f+t), f*100, 30, 30);
    rect(200+150*cos(f+t+PI), f*100, 30, 30);
  }
}
