Pure Black Background for Q10
 

I used to be a theme/wallpaper hound, but as I've matured (read: got old) this became less important to me. I now prefer a clean minimalist look. I found a glossy black wallpaper and resized it for the Q10. The icons really pop against a black background. It also blurs the lines between the screen and bezel, adding to the appearance of a bigger screen.
