Gnome 3 wallpaper based on the current sky color
The shell script does the following:
- Backup the current background.
- Grabs a pic from a local webcam. You should change the URL for a webcam that is local to you
- Crops off the part of the webcam pic that is NOT the sky. This way everything that remains is part of the sky.
- Calculates the average sky color
- Colorizes the black & white png using the sky color
- Creates a Gnome background XML file to gradually transition the previous background to the new one.
- Tells Gnome to use the new XML file and images
