For all the good qualities of the Clojure group, it can sometimes produce a bit of a harsh tone. Don't let that get you down though, it's great that you're building stuff and showing it off!
As far as defun goes, it looks interesting. The out-of-the-box pattern matching was one of the things I enjoyed with ML. It's usually a quite tidy way to handle the termination conditions of recursions. It's less useful in Clojure, since we're more or less confined to loop and recur, but I still like the looks of this.
