This is probably the world's tastiest QR code ever! To celebrate New Year, Chinese Internet company Tencent commissioned a giant cake shaped like a QR code and served it to 20,000 people:
The cake, which takes up a floor area of 36 square meters and weighs three tons, was produced by Tencent, an Internet and smartphone value-added service provider, and Ebeecake, a local bakery. It took ten hours to finish the QR code pattern on the cake's surface. By scanning the QR code pattern, smartphone users can download and install Tencent's news service client onto their gears.
