I actually want to rate as 3.5/5

I really wish you weren't limited to background color.
I think if you could add the more "fun" widgets as a full background: matrix,fireworks,snake,etc. I could actually see more use outta this.

Maybe an ascii image? (images made from alt code or numbers and letters)

I still think this addon has a lot of potential as a fun replacement if someone wants something like this.
I just personally am more of an image/video slideshow type guy.
