Dean Robinson wrote the Fluency 2 Admin theme for Wordpress 2.7. I made a few quick changes so this will run from mu-plugins folder.
Not my ideal solution but at least it is less cluttered and easier on the eye than the default admin theme.

Extract so wp-fluency-2.php and wp-fluency-2 folder are in mu-plugins folder.
Use at your own risk. ;)
