There's currently much ado about the innovative, eco-friendly architecture firm Snøhetta. Based in Oslo, the two-decade-old outfit counts the harmonious, ohh-inducing beauty of the Norwegian National Opera and Ballet and the mega-slanted Bibliotheca Alexandrina as past accomplishments. Yet it's the up-next list that truly demands attention, leading off with the National September 11 Memorial Museum Pavilion. This exhibition opens the Midas-touched doors of Snøhetta to publicize the many ins and outs of 11 important projects through computer visualizations, films, photographs, drawings, models, and an interactive table.
