I just wanted to contribute a .png image that I made for an app that many of you may have already. The Guake drop-down Terminal.
In preferences>Appearance>Background Image, you can add my Antergos image if you like. The Antergos image, I myself got from the Internet but after I converted it, I did a little bit of playing around with it using Inkscape (not much).
Just a small contribution to the rest of the Antergos community.
The picture is very light so it does not interfere with any work while in Guake.
Help yourself to use it if you like.
