Best Graphical Interface for Autodock?

I am trying to find a graphically powerful and versatile viewing
 application to use in conjunction with Autodock; specifically for use in
 drug discovery.  Any suggestions?
 I would like to restrict my search for apps that are FREE and Linux
 friendly.
 I've just started looking, but the best I've found so far is MolMol.
 Thanks in advance for your opinions.
