Illuminating strips of lines

Sorry for the crap title, but I don’t know how to describe this.

Thats an example of what I want to do, if you pay close attention to the hands they become highlighted, but only in a small strip, and it travelles down the hand.

I actually bought that template and was going to edit it, but it’s made with flash mx, and I have flash 5.

I’ve downloaded the trial and see that the whole background in one solid colour, the hands, menu and all.

Thanks for any help.
