For those looking to get started with Clojure, I've created a screencast tutorial series that walks through the Clojure Koans exercises. The koans introduce twenty key elements of the language. I create one video per lesson, so you can watch and learn Clojure in bite-size pieces:
The entire YouTube playlist is here: Clojure Koans Walkthrough
Even if you never use Clojure in your day-to-day development, the ideas explored in the Clojure Koans series can expand your horizons in any programming language you use.
Watch the videos and have fun.
