Wallpaper Engine: do you use it?

It’s a $3,99 software that allows you to pick an animated wallpaper for your computer, with a sizeable bank of user-made wallpapers already available to download for free.
I’ve used it to mirror the “clouds” background option in StarCraft as my wallpaper. It looks dope. It can even come with music, although you can choose to mute it of course.
I may be late on the party, but I figured maybe some of you don’t know it exists and may be interested.

My girlfriend uses it, she has a Tychus wallpaper.
