25
26@does:
27This plug-in makes any element you want "vibrate" every now and then. Can be used in conjunction with blink for maximum annoyance!
28
29@howto:
30jQuery('#ad-area').vibrate(); would make #ad-area vibrate every now and then, options are available, please check the source.
31
32Vibrate currently only works with elements positioned 'static'.

34@exampleHTML:
35I should vibrate every now and then

38jQuery('#jquery-vibrate-example').vibrate();
