QR Code for Developer Jeopardy

Actually found a good use for a QR code in a Jeopardy implementation being used for Mack Flavelle's Developer Jeopardy meetup. Players can join the game by navigating to a shortened URL or by using a QR code displayed on the main screen.

Kazuhiko Arase provides QR code libraries for several platforms including Javascript so there's no need to hit a web service to do the work for you. A great option to avoid the QR code generator from Google Charts' deprecated Infographics API, too. Thanks, Kazuhiko!
