Iridium fits the bill to make Tiger roar with consistency.

I've been an occasional ShapeShifter user, but without intending any insult to all the work that the SS community does, I never found a theme that was undistracting and maintained all the subtle, complex and important steps of contrast that Iridium provides.

I love your new unified look for the OS. Between Aqua for Carbon and Cocoa, the random brushed metal and the "Pro apps" appearance, Apple can make it hard for new users to find their way around sometimes. ("Why does every Open/Save dialog box look different?")

I'm fine the very occasional UI exception, like GarageBand, but in general, there is no need for Apple to be so arbitrary about applying its own themes.

It was Apple (well, maybe it was only Bruce Tog? http://www.asktog.com) who wrote the book on consistent UIs and it is sad to see them stray so far from those prefectly reasonable principles of consistent, predicable UI design.

Your excellent theme restores my piece of mind so I can stop trying to figure out which app window is peeking around the corner from the background based on it's skin and I find myself just using the dock or the Command-Tab app switcher more often, the way it should be.

Install was not a problem. Dropped ShapeShifter along the way. Thanks for that, too. Happy to leave it behind.

Iridium 1.4 is perfect 5 across the board.
