Topic: Using a .swf file for a background and NOT just an image file???

Can I use an .swf for my background instead of just a plain image file?

If so, how do I do it?  I am not a developer so put it in terms I can understand please.

Is this the right code?
background-image:url(water-effect.swf);

Also, I know TiltViewer is being updated.  Any idea on when the next version will be ready and do I have to pay $45 again for any upgrades?
