I haven't touched Clojure yet, although discussions on HN have made me interested, and getting a solid grasp on functional languages seems like the next logical step in my evolution as developer. If you had to point a newcomer to a single 15-30 minute resource - blog post, tutorial, code sample, whatever - that can give them a true "aha!" moment about Clojure, what would it be?

Frankly, I don't think such a thing exists that matches your constraints. Maybe if you're experienced with FP and with the JVM, I suppose? but the 15- to 30-minute aha! moment? If anything I'd recommend reading Joy of Clojure.

Two articles for a start (I'm currently reading the second one, after getting excited about Clojure with the first one :) http://thinkrelevance.com/blog/2009/08/12/rifle-oriented-programming-with-clojure-2.html http://thinkrelevance.com/blog/2009/08/12/rifle-oriented-pro... http://java.ociweb.com/mark/clojure/article.html#Intro http://java.ociweb.com/mark/clojure/article.html#Intro

I recommend Rich Hickey's presentations on Clojure: (Part 1): http://blip.tv/clojure/clojure-for-java-programmers-1-of-2-989128 http://blip.tv/clojure/clojure-for-java-programmers-1-of-2-9... (Part 2): http://blip.tv/clojure/clojure-for-java-programmers-2-of-2-989262 http://blip.tv/clojure/clojure-for-java-programmers-2-of-2-9...

Rich's talk at the JVM language summit, "Are We There Yet?", gives a really good look into some of the ideas that underlie clojure. It's worth viewing even if one never uses clojure. http://www.infoq.com/presentations/Are-We-There-Yet-Rich-Hickey http://www.infoq.com/presentations/Are-We-There-Yet-Rich-Hic...

I don't know about 15-30 minutes, but for anyone interested in learning Clojure, I have collected these links that I found interesting: http://www.youtube.com/watch?v=Aoeav_T1ARU http://www.youtube.com/watch?v=Aoeav_T1ARU http://blip.tv/clojure/clojure-for-java-programmers-1-of-2-989128 http://blip.tv/clojure/clojure-for-java-programmers-1-of-2-9... http://4clojure.com/ http://4clojure.com/ http://www.ibm.com/developerworks/podcast/ag/gloverseries-halloway.mp3 http://www.ibm.com/developerworks/podcast/ag/gloverseries-ha... http://www.infoq.com/presentations/Value-Identity-State-Rich-Hickey http://www.infoq.com/presentations/Value-Identity-State-Rich... http://clojure.blip.tv/file/4824610/ http://clojure.blip.tv/file/4824610/ http://clojure.blip.tv/file/4457042/ http://clojure.blip.tv/file/4457042/ http://vimeo.com/11236603 http://vimeo.com/11236603 http://www.infoq.com/presentations/Clojure-in-the-Field http://www.infoq.com/presentations/Clojure-in-the-Field Visit them roughly in order. As for books, there are a few good ones, but I acutally recommend the documentation on clojure.org more than any book. It's clear and compact.

If you are already familiar with another lisp check out Rich introducing and discussing the language in detail: http://blip.tv/clojure/clojure-for-lisp-programmers-part-1-1319721 http://blip.tv/clojure/clojure-for-lisp-programmers-part-1-1... http://blip.tv/clojure/clojure-for-lisp-programmers-part-2-1319826 http://blip.tv/clojure/clojure-for-lisp-programmers-part-2-1... transcript: http://clojure.googlegroups.com/web/clojure-for-lispers-transcript.txt http://clojure.googlegroups.com/web/clojure-for-lispers-tran... It's not 30 minutes but it's what pushed me past using it on side projects to using it whenever possible and advocating it.
