Post a beautiful Metro picture
It can be any screenshot in Windows 8, Windows Phone, an app, a MS website....anything Metro that you love. I think MS has hit gold with this design philosophy btw.
Some of my favourites:
THE WEATHER APP FROM WIN 8 (HANDS DOWN FAV):
ZUNE (THE GRANDADDY OF METRO):
THE NEW BING; IT'S MY DAILY DRIVER NOW :)
