I’m not a fan of the current default wallpapers in Whonix. The combination of warnings and that mountain takes me back to Win98 (don’t ask me why) and while Workstation looks a bit more modern there is still room for improvement.
Seeing how just recently Whonix logo took under a visual transformation (and looks great now) can something similar be done to wallpapers too?
Perhaps by asking the more artistic members of the Whonix/Tor community for their material or finding something online that has an appropriate licence (Creative Commons 3.0?).
