This is currently the officiall theme for libervis.com portal made out of the default xoops theme. It contains all the original graphics including the libervis logo, but you can replace and edit them as you wish. For the best look i recommend that you replace only the logo.jpg with the same sized image and only edit the head1r.jpg to replace the original slogan with yours.
As this is published under GPL licence you are free to modify this theme and share it as you wish. Also, i would like you to send me any derivations of this theme so that i can implement them to libervis.com if i like it.
