Facebook login locker

Hi guys!
Do you happen to know the name of a wordpress plugin that locks content for registerd users with facebook? I've seen them on any websites but never managed to find it's name. It usually appears with a "Why you no login" meme. Well, it's more like a popup but you get the idea. It makes users register/login with facebook in order to see the content. So do you know one?
I've been searching and found nothing, maybe I've searched for the wrong keywords. Thanks!

I've searched on codecanyon. All I found was like/share/invite users lockers. There probably is what I need too, but I just couldn't find it.

Look for "Facebook Viral App" on that codecanyon site...it does exactly what you want and you also get permissions to post to users walls with it. The same developer also has a sister app that you can use with it where you can require the user to send a certain amount of friend invites to facebook before they can access your content, but I can't remember the name of that app off the top of my head....
