I really liked the Manjaro cat wallpaper included in the KDE flavor (the original artist is muser on https://forum.manjaro.org/) but wanted it spiced up so I made my own. Here are the files I created to make the wallpaper, includes the Inkscape cat svg and Krita file. To create the background I just used the texturizer script-fu in Gimp, get it here. I grabbed the font from here and the Manjaro logo from here. You will need Inkscape and Krita to view some of these files.
If you just want the finished wallpaper at 1920×1080…
The media files can be downloaded from here as a zip.
