This project ccontains two files: a script to be put on the cron 'wallpaper_changer.sh' The second file is conky.conf.defaults, which is just a conky template with some colors defined at the top, and we redefine 6 of them via sed commands in the 'wallpaper_changer.sh' script. Simply put, the defaults are echoed through the sed commands and into the final location $HOME/.config/conky/conky.conf of course, where it is picked up by the line to launch conky at the end of the file.
All you have to do is set up a crontab with this script rotating wallpapers.
This is something I actually had to make twice. I combined an issue on stackoverflow involving gsettings and the gnome desktop, which essentially cinnamon is,

We used this and that to rotate the wallpaper on the cron.
But we missed this

All in all 4 sources combined to do some wallpaper rotation in cinnamon and some rgb swatch rotations into a conky theme.
