Using Actionscript and the drawing API to animate a line (2 points) to 2 new points

hi everybody - what is the best way to go about this?

at its most basic - i need to **animate a line’s beginning and end points using tweener to 2 new points somewhere else on the stage. **

my first thought is to start with the excellent 3d spinning cube example that kirupa made on and backtrack from there.
but i’m hoping to find a much simpler and efficient way of accomplishing what i need.

the problem that i know i need to get around is this… i have to find a way to have the Tweener class give me updated positions of the x and y of the two points which make up the lines. and somehow i have to use the drawing api to ‘get inside of’ tweener to update the stage accordingly - reason for this is that these lines will need to use the elastic tween and bounce around a bit.

i’d appreciate any help

cheers! - tom
