I found this on YouTube, Audi Japan and its sales subsidiary Audi Japan Sales‘s making movie of a huge QR code in gymnasium.
According to Nikkan Jidousha Shimbun [J], this was made in July 2009.
I could read the QR code on the movie with my Android phone with Barcode Scanner app. The code points http://audi.jp/qr , which does not respond. It is too early to finish your campaign site.
There have been many huge QR code ads are all around Japan for 4-5 years.

Blog 2d code told us that the one displayed on the big screen at Cowboys Stadium, Texas, USA might be the current largest. Thanks Roger.

We also got a message from Audi Japan’s twitter account @AudiJapan.
Hmm. Which is bigger do you think? Theoretically projecting on screen can be easily bigger but the one at the Cowboys Stadium seems not to utilize its maximum potential. Both are interesting but I salute to Audi Japan’s as it involves a lot of people and hard work.
