Lately I have been playing around with Metro style templates in Silverlight 4 and I thought it would be cool to share.
This is a free theme based on the Windows Phone 7 Metro style. It's a Silverlight theme, so feel free to download and use for your Silverlight apps or just pull it apart if your keen to find out how it all works.
