/*
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):
