Para quem quiser ir testando, vale a pena.
Mosaic (previously known as Metro Home 2) is an application that brings Metro UI to your desktop. It is a set of live widgets that shows some content from the web or from your PC.
Mosaic supports WPF and HTML(5) widgets (it uses IE9 engine if it installed). HTML widgets are visible only in fullscreen mode (for technical reason).
Currently some widgets are just link to something (e.g. video or desktop or control panel) but in future they could get more functions.
There is one demo HTML widget – Today widget.
Mosaic is in alpha stage and can work unstable
– Windows 7 (maybe works on previous versions, not tested)
– Microsoft .NET Framework 4.0 (Client Profile enough but full is recommended for future versions)
