Animated Themes for Windows XP

How do I create an animated theme for windows XP? I know how to create normal themes, but can't seem to find anythoing on adding animation.

This is what I need:

The 开发者_Python百科Start menu should be themed like an iPhone, so I slide to lock/unlock the start menu.

Any ideas?

I really don't know if this is possible. You might be able to use some of Stardock's products to cobble something together...
