I too would like to know more about the new Guggenheim's architecture.
Are there any articles in architectural journals worth reading?

Two random  things about the museum:

-The titanium portions of the museum (architect: Frank Gehry) were
manufactured by a company which traditionally makes titanium parts for
airplanes (this metal is favored in the airline industry due to its light
weight and exceptional strength)

-The Guggenheim tried to obtain Picasso's Guernica for the opening of
the museum, but the loan fell through. (Does anyone know more about
the specific reasons?)
