A super large cake which bears a QR (Quick Response) code pattern is displayed at a shopping mall in Beijing, capital of China, Dec. 31, 2012. 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.
