No matter what artwork Linux developers use for their distros, you can bet that someone won’t like it. Mepis users have complained loudly about that distro’s default appearances, leading to a huge community effort to beautify things over the past few releases. More here
Like I said, I thought Mepis 8′s default appearance was great; for the first time ever, I haven’t changed the default colors or scheme. But that’s about all I didn’t change. As usual, I put in my own wallpapers, completely tweaked the panel, swapped out left- and right-arrow icons, put in a standard KMenu icon to replace Mepis’ default one, tweaked the clock’s appearance, chose the transparent (dark background) scheme for Konsole, and changed the mouse cursor, among other things.
