I've visited several profiles where the person had several different variations, so that you would see a different profile everytime you visited their...profile.

So I'm wondering how you do this.

You'll need a profile rotating widget. Guide here :)

How do I get one of those?

Sorry...I'm sort of a coding/page editing newbie

Erm. Sorry. I didn't see that part of your post. It's 4 am here and I'm not thinking properly.
