Add Piecemaker to WordPress Header

I wish to add the Piecemaker 3D rotator to WordPress theme TwentyEleven In Header and NOT as a POST or Page. Via WordPress Plugin: Piecemaker 2

Steps:
1. Piecemaker Created with Assets
2. Tested on POST/PAGE. Getting displayed correctly.

Question:

1. How to display it in Header instead Of the TwentyEleven images
   (Header script removed)

What should i do to display the Piecemaker in Header.

I have tried:

1. Adding below code in Functions.php Source: Support forums

   /**
    * Function to use piece maker outside post content
    *
    **/
   function display_piecemaker($att = null){
   global $pm;
   
   if(!is_array($att)){
       $att = array(
           'id' => $att,
       );
   }
   
        echo $pm->replaceBooks($att);
   }
   

2. Calling the function in theme file:

   <?php if( is_home() ) {
   display_piecemaker(array('id' => 1));
   }?>
   

Note: I am beginner with PHP.
