Julython (in January) - a python codemonth with infrastructure, not just culture
http://www.julython.org/ is taking the approach of "gamifying" day-to-day python hacking; you just add a commit-hook that pokes their site, and they assign you "points"... reminds me of http://twistedmatrix.com/highscores/ and https://github.com/icefox/git-achievements a little :-) Running January 2013.
