Ice cube?

A giant ice cube has appeared in Minneapolis and isn't going to melt. Described by its Swiss architect, Jacques Herzog, as "A big ice cube for Ice City," the cube is in fact an extension to the Walker Art Center. The icy appearance of the recently inaugurated silvery 5-storey edifice has been achieved by use of aluminium-mesh panels. Renowned for avant-garde projects, Herzog and de Meuron also designed the Tate Modern in London, a jewel-like Prada store in Tokyo and the 2008 Olympic Stadium in Beijing.
