animated screen as a wallpaper

Hello!

I would just change my 'wallpaper'. I have two questions:

1) Is it possible to have a function to change the screen every 10 minutes for example? If it is not native, is there a program permitting?

2) Is it possible to put an animated screen (like an object that moves or otherwise)? If so, how? And where to find?

A super big thank you for your help!

Ps: I have full vista 32bits

good evening!
