/**
*
* SoundManager 2 Demo: 360-degree / "donut player"
* ------------------------------------------------
* http://schillmania.com/projects/soundmanager2/
*
* An inline player with a circular UI.
* Based on the original SM2 inline player.
* Inspired by Apple's preview feature in the
* iTunes music store (iPhone), among others.
*
* Requires SoundManager 2 Javascript API.
* Also uses Bernie's Better Animation Class (BSD):
* http://www.berniecode.com/writing/animator.html
