This is what Im currently using right now. It was originally robs1968's Ultimate Blue IV theme and I added my own background image which i edited off another. It has the Xp start up sound and VERY NICEE Blue and Green waves which look really cool with the background image.
Basically, you can use whatever theme/sounds etc. you want. Just use the 01-12.bmp and custom waves and place it in any theme you like. It will give you a nice Windows Vista look.
