Macbook Pro with swiveling screen?

To whom this may concern. My wife was talking about a MacBook Pro that has a move able screen the can turn either 360 or 90 degree's. I've been looking around with MacBook Pro's and cant find anything in any of the information. Does it exist or is it just a desktop. If so what MacBook Pro version is it?

Thank you...
