I created http://www.sherbondy.com, a website that gives family members free subdomains @sherbondy.com. Learned Clojure while making it. Wrote the entire thing in Clojure and ClojureScript. Tons of fun. I've even open-sourced it so that others can do the same for their families: https://github.com/sherbondy/sherbondy.com

Still need to fix/optimize a bunch of stuff and better document/test, but it was a nice break from studying for exams. And man am I loving Clojure.
