Need help on creating a line mouse trailer that fades out (CS3)

Hi,
Anyone know any tutorials/script on how to create a mouse trailer in AS2 that gives the effect of the mouse “drawing on the screen”, and fading out after a short period of time?

I’ve been searching online but with little luck…

Found an AS1 version but don’t have a clue about how to convert it!

Any help greatly appreciated! Thanks…
