looking to add animation to the spry tabbed panels

SO I was wondering if there's any way to add a fade in/out to the content panel on the spry tabbed panels, whenever you click a new tab, have that content fade in or do some other kind of effect that adobe supports through the spry framework.

I've already looked at the adobe labs documentation, and I can only find effect modifications for the accordion panels.

Any help would be great!
