A Colourful Dartboard §

void setup() {
  // caleb b
  // a colourful dartboard
  size(600, 600); // set screen size
  for(int i = 10; i > 0 ; i--) { // for loop starts from 10 and counts down so the smaller circles get drawn on top of the larger ones.
    fill((float) (Math.random() * 255), (float) Math.random() * 255, (float) Math.random() * 255); // generate random colours
    ellipse(300, 300, i*50, i*50); // create the circle
  }
}

Draw a Clock §

void setup() {
  // caleb b
  // drawing a clock
  size(550, 550);
  fill(255, 255, 255);
  ellipse(275, 275, 500, 500); // create the clock
  
  int centerX = 275;
  int centerY = 275;
  int radius = 250;
  
  for (int i = 0; i < 60; i++) {
    float angle = radians(map(i, 0, 60, 0, 360));
    // line start points
    float x1 = centerX + cos(angle) * (radius - 10);
    float y1 = centerY + sin(angle) * (radius - 10);
    // line end points
    float x2 = centerX + cos(angle) * radius;
    float y2 = centerY + sin(angle) * radius;
 
    if (i % 5 == 0) {
      // hour ticks
      strokeWeight(4);
      stroke(0, 0, 0);
      line(x1, y1, x2, y2);
    } else {
      // minute ticks
      strokeWeight(2);
      stroke(0, 255, 0);
      line(x1, y1, x2, y2);
    }
