I have some spare time so I decided to make a background and menu bar color. I made them smaller so that they can just be put on "Tile" so they'll fit any screen size.
I uploaded a .xcf of the background to http://www.gamefront.com/files/21175872/Wallpaper.xcf. So go there if you want to download it.
Both of them together look like this
It's kind of girly but oh well, I don't think it looks bad.
