So I did a series of the infinity backgrounds, 24, 1 for each in the day 
to match the approximate sky coloring of that time of day.

All 24 PNGs:

Each one is widescreen, 25600x1600 pixels which I think is the largest 
reasonably available resolution for widescreen ratio. :)

I put together an xml file for the animation based on the format for
gnome-desktop-2.19.90-4:

I did each one using gradients and layer blending modes in the Gimp over 
top of the main background image. The source is here (warning: it's 
quite large):
