A clean, minimalistic administration theme inspired from the new customizer look of wordpress 3.4.1 
It’s pretty basic and adds a css file to your administration.
Since this plugin was created I have used the knowledge that I have acquired to build the bootstrap admin theme, which I would recomend you use instead of this one. 
You can get it here: https://wordpress.org/extend/plugins/bootstrap-admin/
This project was built for the http://magazi.org network of stores.
