Clojure is a wonderful Lisp-like programming language.
I have created a screencast series introduces the language in bite-size pieces, by walking through the twenty lessons of the Clojure Koans project.
Jump right in here: 1. Introduction and Equalities
The entire YouTube playlist can be found here: Clojure Koans Walkthrough Screencasts
Enjoy learning Clojure. You’ll be a better programmer, no matter what language you end up using.
