Backgrounds.appBackgrounds makes your desktop more interesting and useful with 7 themes: Music, Parallax, Video, Quartz, System, Time and Web.

Hide your Desktop icons easily and enjoy your wallpaper. Add time, day and date, along with useful system information graphs to your desktop. Backgrounds includes a Notification Center Today Widget and 2 screen savers.

I really like the Parallax and Video desktop options!
