In June 2012 four ETC students, Elwin Lee, Xiyuan "Zero" Liu and Xun "Eric" Zhang created a Kinect Game "Xdigit: An Arithmetic Kinect Game" for kids. The student's game was accepted to the Fun and Games 2012 conference in Toulouse, France and won 3rd place in the student contest.

"Additionally, I met some people from Australia during the conference who were very interested our game, and invited us to demo it at the Games For Change conference in Melbourne, Australia. Unfortunately, none of us were able to attend the conference, but the organizers were kind enough to have student volunteers run our demo on our behalf.
The conference is actually happening right at this very moment! :)

Nice work, Elwin, Zero and Eric!
