Windows Phone start screen groups concept

Working on a little concept for start screen groups on Windows Phone. Just a prototype right now, have a lot more I want to do with it. (click a group name ((e.g. people, media, etc..)) )

In the future, clicking a group will expand the groups, and clicking on an expanded group would anchor to the correct location. Right now it only does one function.

(it's not going to look good if you don't have Segoe UI)
