openSUSE 12.2 Theme.
This is the original theme to ship with openSUSE 12.2 KDE, with only the wallpaper added and name changed to avoid conflicts.
This does require a little bit of tweaking to make it look right because KDE5 does not follow the same GUI layout as KDE4.
Changing the taskbar size to be a little bit smaller (32 pixels for me), and changing the task manager from "icons only" helps as well.
The original 12.2 wallpaper is in the theme as well as the preview gallery.

Known Issues:
Theme does not uninstall correctly with KDE 5.22. If the theme will not uninstall with the System Settings, you can delete openSUSEdefault12.2 from ~/.local/share/plasma/desktoptheme (KDE5) or ~/.kde4/share/apps/desktoptheme (KDE4)
Application Launcher icon does not apply correctly. It is located in the theme files as start.svg
