This is a pretty neat video of not only the Windows Phone 7 lock screen for Android, which is being worked on by the guys at WP7Android, but they have managed to build a Windows 8 live tile look too with Desktop Visualizer and ADW EX on a Galaxy tablet, running Honeycomb 3.1. Apart from the stock Android style clock and icons on the bottom left (which I cannot stand personally) what they've managed to achieve with the tiles is really impressive.
