Someone mentioned that you had to look at the source code if you wanted to hack your badge this year; I would have considered that cheating if I hadn't known.  (It's been a few years since I last hacked my badge).  But it helps if you look in the right place: http://lca2012.blogspot.com/2011/09/feeling-silly.html

Thanks to Tony Breeds for pointing me at that after I'd given up with the github upstream source...
