  If you run the application with only the code up to here, the scene appears empty. This is because a Node is invisible, and you have not yet attached any visible Geometries to the rootNode. 
  
  
  .  Attach the two boxes to the pivot node.

  If you run the app with only the code up to here, you see two cubes: A red cube straight above a blue cube.
  
  .  Rotate the pivot node.

          pivot.rotate( 0.4f , 0.4f , 0.0f );

  If you run the app now, you see two boxes on top of each other – both tilted at the same angle.
