Fading Background Image

I thought this might exist already on the forum but I couldn't find it. Has anyone had success implementing a fading background image? Basically, something like the rotating header image but something for the entire background.

I'm thinking there's probably a way to do it using a JQuery plugin like Premium Slider. There's also the Better Backgrounds plugin, though I've read it has some compatibility issues with Atahualpa 3.7.1.

One thing I thought about was using a slider plugin and activating the right sidebar, giving it an actual width of 1 px and just having the actual image be gigantic, big enough to cover just about any resolution.
