I’ve been searching Google and this site for tutorials for this and can’t find anything which seems to fit what I’m looking for. I’m trying to divide the screen in 2 and then allow user to rollover the middle of screen - when they do, depending which direction they drag, the bottom or top of the screen bulges and then springs back into place. I’ve created this mock-up:

Wherever the user rolls over which the mouse, that is where the line bulges.

I have tried this tutorial:  
[http://www.kirupa.com/developer/actionscript/spring.htm](http://www.kirupa.com/developer/actionscript/spring.htm)

but I can’t figure out how to get from a single ball to a solid block which bulges at different points depending on where the mouse action is.

I really can’t figure this one out so any help or ideas would be much appreciated.

Thanks all.
