I can't think of what it's actually called, and I can't remember which one of Jay's webinars mentioned it. I'm looking for that free site that allows you to create a book cover or a  3d box - one of those standard product label type things - and you'll often see a 'get your free guide' attached to it somewhere and a way to sign up for a list.

I'm not sure if anyone knows what I'm talking about.  If so, what's the site?
