Wolfbane skin has a very nice style in my opinion. Unfortunately, this skin seems no more mantained by original author (Stinkfly), so I made a derivated version.
New Wolfbane has many modifications respect original one. Here most important changes:
This skin works fine also in mediawiki 1.18, but you must remove this line in wolfbane.php:
<?php print Skin::makeGlobalVariablesScript( $this->data ); ?>
Unpack the .tar.gz in /skins and set in Localsettings.php:
$wgDefaultSkin = 'wolfbane';
If PHP is installed as CGI (and not as module), add these lines at beginning of Localsettings.php:
error_reporting(0); ini_set("display_errors", 0); $wgShowIPinHeader = false;
