Based on a very nice RedHat wallpaper (around version 8.0), I couldn't find a better image than this one:

I would like if someone with better graphics skill could make a more glossy/sharpen/overally better wallpaper.
Maybe with diffrent colors, and diffrent logo, diffrent sizes... any variation on the theme as long as it looks nice.

Cheers.
