Looking for help: Porting Aero to GTK

I've been experimenting with re-creating the Windows 7 look and feel in Gtk using CSS. It looks super realistic now that Blur My Shell exists!

Please feel free to download the demo off my github and give it a spin! Also, if anyone would like to help with porting some widgets I'd be very greatful! There is quite a lot that I haven't yet managed to style.
