hii, Paypal has one, we tried to run it but it feels a little distracting.Not sure if I can post a link but it's a 4 second loop under our main intro page sales jargon.I actually dislike it, but I have seen a few sites do that now. I believe Paypal was the first one I saw.My perspective is that it is distracting like you mentioned.Feel free to post the link.I just checked Paypal's and theirs stops like yours does. I could have sworn in the past that it kept going and going, maybe they found that at some point the distraction should stop? Not sure.
Thanks!
I didn't find the right solution from the Internet.
