Anime Window Theme/Sound Packs?

Has anyone ever found or is using Anime based Window Themes? That can include custom wallpapers, boot up screens, login screens and custom sounds that replace Window sounds that are Anime based?

I seen a few, like there is an Angel Beats! screen server and you can easy change the wallpaper for boot's and login screens.

I be making a big google search soon, but till then, anyone else already using something?
