Very nice 2 pages cheat sheet by Steve Tayon http://clojure.org/cheatsheet and pdf http://cloud.github.com/downloads/richhickey/clojure/clojure...

That's quite a bit outdated, though.

Looks good, but what happened to a small reference that fits on a single fan-folded card? Many 'cheatsheets' as good as they are, were they to be printed would be longer than the classic K&R C Language Reference.

I also use this Clojure Quick Reference: http://faustus.webatu.com/clj-quick-ref.html

This looks very useful. Nicely done.
