+ 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):
