I am glad that I could participate the Christmas Experiments last year in 2014. My experiment was Christmas Card to Everyone. It allows you to customize your own Christmas cards and share it to your friends! It was also the first experiment that contains sexual content and strong language as far as I know. Christmas Card to Everyone shows you
how unprofessional I can be and how to make a silly joke in a serious way. Well, of course it also allows you to spread your Christmas spirit to your friends.
