The GNOME-ish program Déjà Dup (a usable backup UI) could use some better icons. I filed a bug about it in its bug tracker.
The general gist is that it could use a revamped logo and possibly better icons for both backing up and restoring. I'd like an artist either to say "I love these icons, what are you talking about?" or "Gosh, these suck, here are some suggestions/icons".
I'm the maintainer. My contact information is on my launchpad account. Thank you!
