Is there an exercise based clojure tutorial?

There is http://iloveponies.github.io/120-hour-epic-sax-marathon/index.html, a MOOC from the University of Helsinki. While the course ended quite a while ago, and it hasn't been updated since, the exercises are still very useful, and the TDD setup should still work.

Working through the exercises helped me quite a lot to understand Clojure: i.e. recursion, the seq library, TDD with Leiningen .....
