the "metro" UI model is not quite what some folks think it is....
if you check the design style for Win 8 and Win Phone came from some of the style of Media Center and how it's UI was clean, simple and used no pop up windows to show new views.
so I would take a look at MC and XBOX and Win 8 and look at what they share and then look for designs that use the best of how they are styled, and keep in mind that folks tend to copy demo code and not try to make a real design.
+1/Like/[whatever since C9 doesn't have this feature]
Metro isn't about using just 2 colors in an app. It's about anti-skeuomorphism.
