Rotate 1. Rotating simultaneously in the X and Y axis. Transformation functions such as rotate() are additive. Successively calling rotate(1.0) and rotate(2.0) is equivalent to calling rotate(3.0). 

  
   
  float a = 0.0;
  float rSize;  // rectangle size
  
  void setup() {
    size(640, 360, P3D);
    rSize = width / 6;  
    noStroke();
    fill(204, 204);
  }
  
  void draw() {
    background(0);
    
    a += 0.005;
    if(a > TWO_PI) { 
      a = 0.0; 
    }
    
    translate(width/2, height/2);
    
    rotateX(a);
    rotateY(a * 2.0);
    rect(-rSize, -rSize, rSize*2, rSize*2);
    
    rotateX(a * 1.001);
    rotateY(a * 2.002);
    rect(-rSize, -rSize, rSize*2, rSize*2);
