Textures of Shanghai Expo

In 2010, Shanghai had a big cultural/ tourism/ architectural/ technology exhibition, called the Shanghai World Expo. It was a huge event that can drew millions of people to pour down the expo site. Despite the summer heat and sweat, and never ending queues, to visit the expo was still an interesting experience. Mostly because  we can learn bits and pieces from different countries. It was like scanning the world through miniature models. The one thing that I found quite interesting are the textures and patterns featured there.
