It would be very nice if each koan had docs included underneath (maybe hidden by a hint link?) talking about what the koan was trying to teach you. If you can do every single one it isn't that much fun, but if you can't do every single one then you need to go off and learn something and it would be really good to help nudge the user along to where they can learn more. Alternatively to a help box having the displayed code provide links to the appropriate clojure docs would be another route.
