How do you get random footers on these boards?

Not sure if this is the right place to ask this question or not.

I see several people with a footer that rotates when you refresh the page and was wondering how they did that. I'd like to make more footers for my account here and show them off while making posts!

They're called "Sigs", and you can do it with this website: http://ultrarandomization.com/
