Stripe effect how to

Hello everybody!
I’m new to this forum though I’ve used Kirupa fantastic tutorials several times!
I’m quite a newbie in Flash and I’m italian so many excuses in advance for my bad english! I’ve seen an effect in a template on templatemonster.com, the template is Flash Template #10054. When you click on “play presentation” an effect of fading stripes start revealing the images below, I think it uses mask and maybe some AS as well. Thanx for any advice!

Hi to anyone reading!
I found this tutorial in kirupa tutes section:
http://www.kirupa.com/developer/mx/fadegrid.htm
this seems to answer to my question about the “stripe effct” I was talking in my first msg.
Is this the only way to obtain the effect?
