Hello!
I’ve made a dynamic wallpaper based on the no-logo Ubuntu MATE stars. (included)
It (really) is GNOME’s Adwaita “day cycle” background, but modified for this distro.
[ubuntu-mate-timed.xml][1] (onedrive.com)
XML document (application/xml) 1,810 bytes
To use it: Go to the Backgrounds Tab under Appearance Preferences, click Add, select All Files from the drop down menu next to the OK / Cancel buttons, and navigate to and select the XML file.
Why, yes sir!
I specially had a lot of trouble coding a sunset in, since we generally say a day has 24 hours and not 86,400 seconds, yo.
Feel free to remix and respin and dismantle it and remantle it again!
