	SoundManager 2 Demo: 360-degree / "donut player"
	------------------------------------------------

	http://schillmania.com/projects/soundmanager2/

	* Beta-ish warning: Subject to flux. *

	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
