Comment 14 for bug 827426

Instead of just describing what the new icons should look like, I've modified the ones I linked to in comment #9 to match oneiric's theme and add transparency. Attached. To try them, untar the archive in ~/.icons and run

dconf write /org/gnome/libgnomekbd/indicator/show-flags true

I will also attach the script and data I used to generate these flags and a screenshot of what this looks like in oneiric, both in normal mode and when the dash is open.
