If someone is intrested, I updated the library with an example and an gifDecoder.
You can select a gif and it will automatically run as your wallpaper.
Now it's started to look more like a LiveWallpaper and a nice addition to Erel's excellent LiveWallpaper Library!.
I used JD-GUI on Agraham's GifDecoder, and I hope I was allowed. Agraham, tell me if I can use it, otherwise I will remove it.
