This book presents a new chapter in a series of installations that different visual artists and architects from around the world created in Mies van der Rohe"s emblematic building. The Chinese artist Ai Weiwei filled the pavilion"s pools with two typical items that are part of our daily lives, but are completely at odds with an architectural construction: the water in the pools, one exterior and the other interior is replaced, respectively, with milk and coffee. Ai Wei Wei was born in 1957 in Beijing, where he currently lives and works. His work has been shown in a large number of museums and galleries, including the Faurschou Gallery in Beijing, the Haus der Kunst in Munich, the Mori Art Museum in Tokyo, Ivorypress Art+Books in Madrid and the Beijing Center for Photography, among others.
