I've said this before and will say it again. Cover disks of monthly magazines often (actually just about always) have animated backgrounds on them.

In truth, the cover disks, are the best bit lately. I do tend to glance therough them over a nice coffee and (more and more) find that the assets on the cover disk are more than worth the costs of the mag.

You would need to check the licencing on them before using them for anything you're likely to make money from I suppose.
