Just like HTC Home, the same developer of HTC Home, has another interesting weather and clock widget, called the Metro Home. Metro Home is a special version of HTC Home with dynamic interface in the Metro style, which is identical to Windows Phone 7 UI (Windows Phone 7 fans should love this).
http://www.htchome.org/en/downloads/metro/Metro Home 2 is free for download and works on Windows 7 and Windows Vista only (32 or 64-bit operation systems).
It requires Microsoft .NET Framework 4.0 to work.
