Hide site logo on index.php

Hi all,

How can i hide my site logo so its not visable on index.php (home page) but visable on all other pages?

Pretty much i dont want guests to my site to be able to see the logo when they first come to my site.

Thanks in advance :)

If you are looking for an easy answer I don't think there is one.

What about a custom splash page that everyone lands on and signup/login there?
