In this exercise, we were to create an ornament which can be extended in all directions. In a kind of way, this is also extend-able but not in any way symmetrical. It still is pretty in such a way that the motive gets thicker when several of them overlap.

void setup()
{
  size(600,600);      // def. fenstergroesse


  smooth();           // aktiviere antialiasing
  strokeWeight(1);    // linienbreite
}

void draw()
{
  background(255);    // def. hintergrundfarbe
  float rotator =0.0;
  int fade = 0;
  fade+=1;
  for(int x = 0; x <= width; x+=50)
  {
    for(int y = 0; y <= height; y+=50)
    {
      pushMatrix();
      translate(x,y);
      scale(.3);
      //smiley();          // funtions aufruf
      graphic((int)random(2000), 0, 0,(fade%100));
      popMatrix();
      fade+=1;
    }
  }
}

void keyPressed()
{
  switch(key)
  {
  case 's':
    save("screenShot.jpg");
    println("save the screen to screenShot.jpg");
    break;
  }
}

// funktion
void smiley()
{
  noFill();
  ellipse(0,0,180,180);  // kopf

  fill(0);
  ellipse(0 - 30,0 - 30,20,5);  // linkes augen
  ellipse(0 + 30,0 - 30,20,5);  // rechtes augen

  noFill();
  arc(0,0,100,100,radians(20),radians(180-20));  // mund
}
//funktion
void graphic(int amount, float x, float y, int al) {
  float a = 0.0;
  float inc = TWO_PI/100.0;

  beginShape();
  vertex(x,y);
  for(int i=0; i<amount;i++) {
    stroke(0,0,0,al);
    vertex(x+=(sin(a)*5*cos(a)*6)+0.1,y+=(cos(a)*5+0.1));
    rotate(PI/4);
    a+=inc;
  }
  endShape();
}
