Comment 29 for bug 276594

The current wallpaper is tasteless, ugly, and gives the wrong impression to someone who is trying Ubuntu for the first time. The current choice of the wallpaper conveys a message of "unprofessional" quality that will cause many first timers to steer clear of even trying Ubuntu.
There are countless better choices out there, even just within the Ibex community art, and the Gnome-art pages.

Releasing Ibex with this choice of wallpaper is an irresponsible decision that needs to be reviewed in my opinion.
