[Dynamically change target of timeline]

Ok thanks to you both. The solution wasn't exactly what I needed but it got me down the right path to finding it. Thanks guys!

[Dynamically change target of timeline]

I am trying to create a timeline where the target can be updated dynamically. When .play() is called, I want what is tweened to be based of the current $(this) jQuery object. The way I was attempting to do this does not seem to work.

Is there a way to use a argument or parameter for this?
