Ask HN: Interesting Lisp/Clojure articles for experienced programmers?

[rustc]

HNers, are there any interesting articles (or short books, or chapters in a book) that would show me the power of Lisp/Clojure, and make me really want to learn it?

(Better if a free resource, but not really necessary.)

The Joy of Clojure is fine, and maybe even exciting in parts. It's worth the money, or you can have mine (hope that's not discouraging).
