/*
 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):
