How do they make the banner flash?

I was bored today so I looked at the NB ads with no intent of buying. The 4th post down is the Cosmic Marketplace, and somehow they have their banner flashing. How do you do this?

You could take each picture as layers and use Adobe Imageready and go through each frame. It is probably 7 frames. 1 for each letter for Cosmic and probably 1-2 more

You could download Gimp, it's just like Photoshop except completely free. That's what I use for all my graphics needs
