From the previously posted video on the little application written for Google Account / Drive intergration as seen below
Tom Beckmann, the developer behind Gala and GDrive app uploaded a screenshot with Google Drive interface being elementary-fied with some tweak done to the css file

Looking great !
The application is being available in bzr @ lp:~tombeckmann/+junk/gdrive but to try this app will requires you to enable Gnome-Online-Accounts plug and having Google Account being setup. Though, there might be possibility that the application might not function properly as expected.
