Live wallpaper windows?

I would like to have a live background on my laptop, to be precise a sound visualizer that adapts to the sound. I've tried Lively Wallpaper, but nothing good comes out of it. What other options do I have?

Wallpaper Engine is the best I know. Available on Steam.

But I don't want to spend any money on it. I only find paid apps on Steam, except for Dino backgrounds

Well, then unfortunately you were unlucky.
