An ongoing exhibition examines the economic, social and cultural transformations of the BRICS countries. The works on display show how artists react to these shifts. Lin Qi reports.

Belgian artist Wim Delvoye is known for inventive but controversial works through which he reflects on the problems in a globalized world. The 52-year-old's mix-media installation, Cloaca No 5, is a machine he created with help from scientists, computer experts and designers. It mimics the human digestive system.

The device was assembled with parts manufactured by factories in different countries, similar to how many industries operate today.
