Help please.

I was wondering if anyone out there knew how to make a line draw itself in flash...if that makes since...like a siggly line that you cant see at 1st then it fills it self so you can see it...sorry im new to flash, im a ps/cd4/ir freak so flash is like a different language to me. that would be great if anyone knew a tutorail or anything around that poorly explained explaintion of what i would like. thanks ~whale

The easiest way would probably be to draw a squigly line and use an object tweened in a mask layer to make it show up.
