Some of these groups are exclusively devoted to Clojure, others list Clojure among its interests. Some places have people waiting for others to join them in starting a group. There may be one or more near you!

A Clojure-based statistical computing package and graphics environment for Clojure and JVM.

Labrepl is a tutorial environment for learning clojure.

Announced in the clojure google group, uploaded to github. An easy installer was suggested in the discussion.

Jline may be used on top of the standard clojure repl, as mentioned at http://clojure.org/getting_started. It adds history walk and minimal editing.

Jline can be downloaded at http://sourceforge.net/projects/jline/files. Get the latest version (the download button will not necessarily show the latest one).

Example usage in Windows:

java -cp "c:\Program Files\Clojure\clojure-1.1.0\clojure.jar";"C:\Program Files\Clojure\jline-0.9.94\jline-0.9.94.jar" jline.ConsoleRunner clojure.main

Example usage in Unix: see http://clojure.org/getting_started.

Read about it at http://github.com/richhickey/clojure/blob/1.1.x/changes.txt as well as http://clojure.blogspot.com/2009/12/clojure-11-release.html

Clojure is a modern Lisp, two years in the making and counting. It runs on JVM (desktop Java runtime) and thus bridges two worlds: the widely used and well optimized modern virtual machine (with Java API readily available) and one of the oldest and most elegant programming languages (Lisp, born in 1958).

Language advocacy is not the best way to spend a programmer's time; learning the craft is better, and writing programs is best. Have fun and good luck!
