This is the concept of a Facebook client designed for Windows 8. I think this app would be useful and good-looking at the same time.
The titles at the top are categories, similar to the Zune software.
As Windows 8 will show the user's profile picture in the task bar I decided not to show the user's Windows Live ID in the title bar like in Zune (which would also not make too much sense on a Facebook app) and replaced it with the Facebook-logo (the "tile").
I have got inspired by Conner-Monsees' [link]
work. He makes really awesome concepts.
