The best World’s Fairs have served as seedbeds for innovation. The Hanover, Germany 2000 World Fair was among the best. One of the architectural highlights of the fair was Bertelsmann’s Planet M: a remarkable ovoid shaped building clad in Escale stainless steel designed by Triad Architects. In the daytime, the light-reflecting skin glistens, and in the evening the building glows from within as the mesh recedes into the night. Photography copyright 2001, Wolfgang Schwager.
