A new version of the Module PageRank for Joomla is available on gelbfisch.de

This module will display the Google Pagerank of a URL which you can specify in the parameters.

In the current version 2.0 you have the option to switch between text-output and several graphical styles. As an alternative you can choose a special color layout and define the back- and foreground color of the pagerank out of 8 predefined colors.

That should be good enough to adjust the output to all colorful templates out there.
