Snail-like houses on display in E China

Children sit in a two-square-meter ambulatory house named the "mimi villa", which is on display at Human Settlement Exhibition in Hefei, east China's Anhui province, on May 1, 2010. This snail-like house, believed to be the smallest house in the world, is designed by a low-carbon enthusiast. It can be turned into either a writing table or a reception room and also comes with cooking utensils, allowing people to prepare their meals.[Photo/CFP]
