Clojure editor/IDE recommendations on Mac OS X [closed]

Question

I am starting to learn the Clojure programming language. Are there any recommendations for Clojure editors/IDEs on Mac OS X?

Update 2009-09-23: The Clojure space has changed tremendously since I originally posted this question. Many of the links below, especially those that refer to clojure-mode with Emacs, are out-of-date. The best Clojure IDE I found was the Enclojure Netbeans plugin which was recently released (2009-08-25).

Update 2010-04-30: Another very good article on this subject is Clojure IDEs - The Grand Tour by Lau B. Jensen. Also, for my own clojure development, I have actually moved to Emacs / swank-clojure.

For setting up Aquamacs, Slime and Clojure, there's a screencast on lispcast.com:

Edit: That's a nice alternate screencast you found Jman. I've added it to my answer so it's a bit more comprehensive.
