Here's the FAQ and here is the custom mood editor.

And all my LOTR icons are here (A-L) and here (M-Z), if you want to make different choices for each mood than I did. I will continue to update these pages if/when I add more. Again, I'd prefer for you to copy which ever icons you like to your own hosting service, and then use the custom mood editor to make your own mood set. If/when you do, let me see which icons you picked.
