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):
