I was looking for a sweet looking metabar theme, and although those made for kubuntu aren't that bad, i'm using gentoo, so I thought the curved one was good, but link was dead. So I found simply, which was perfect for me, except the gray theme didn't matched my blue coloring scheme... so I modified the css so that it matches my color. Hope someone likes it!
To install globally: extract the archive in /usr/share/apps/metabar/html
To install locally: extract the archive in ~/.kde/share/apps/metabar/html (you'll have to create metabar/html first)
Note: The two files within the archive aren't in a directory so extract it from the html directory to make sure it goes where you need it.
PS: I have an lcd screen, so the blue may differ on your crt, keep this in mind.
