best theme Rated 5 out of 5 stars

I change skins and themes like crazy and in Firefox I have to go back to this. Simply the coolest! Anybody knows one like that? I would like a flat sleeky one? The old green miint was intersting but abandoned years ago. Reins is now supreme for the good taste users. Does anybody has another favorite from this kind?
On the rein's site I noticed something about a 'iP! 2.150 Firefox Theme". It seems cool dark i would like to try it. Does anybody knows anything about that one?? (just look: http://notiz.jp/wordpress/wp-content/uploads/2011/09/ip20.png)

This review is for a previous version of the add-on (5.1.7).
