2. Add the following temporary variable and code to the simpleUpdate() method:

   float temp;
   public void simpleUpdate(float tpf) {
     // a trivial 2-second timer
     temp+=tpf;
     if( temp>2 ) { restartDemo(); temp=0; }
   }

3. Add the following custom demo method:

   private void restartDemo() { settings.setResolution(FastMath.nextRandomInt(100, 800),FastMath.nextRandomInt(100, ...
