Another way is to pick a top-notch library or framework in your target language, and learn to use that. For Clojure, I'd try making some clever charts with Inca

Another way is to pick a top-notch library or framework in your target language, and learn to use that. For Clojure, I'd try making some clever charts with Incanter: http://incanter.org/ http://incanter.org/ (Incidentally, the only new language I've been able to stick with after learning Python is R, because it solves completely different problems. Which means R is now my Blub for stuff that I'd like to, given some free time, try with Clojure/Incanter...)
