Cloud Gate in Millennium Park, Chicago

Cloud Gate is a public sculpture by Anish Kapoor in Millennium Park, Chicago. The sculpture is shaped like an ellipse, and its legume-like appearance has caused it to be nicknamed “The Bean”. It is made of 168 highly polished stainless steel plates, and stands at 33 feet high, 66 feet long, and 42 feet wide, weighing 110 tons. From a distance it could be mistaken for a huge drop of mercury, while up close its highly reflective surface captures and transforms the skyline, the downtown cityscape and even the passers-by into a wonderfully warped new vista.

The artist, Anish Kapoor, has referred to the sculpture as “a gate to Chicago, a poetic idea about the city it reflects.” The 12-foot underbelly is called the "omphalos" or navel and multiplies reflections in a vortex.

National Grand Theater, Beijing, China

Designed by Paul Andreu Architect, the National Grand Theater of China is Located near Tiananmen Square , the 490,485-square-foot glass-and-titanium National Grand Theater, scheduled to open in 2008, seems to float above a man-made lake.

Intended to stand out amid the Chinese capital's bustling streets and ancient buildings, the structure has garnered criticism among Bejing's citizens for clashing with classic landmarks like the Monument to the People's Heroes (dedicated to revolutionary martyrs), the vast home of the National People's Congress, or Tiananmen Gate itself (the Gate of Heavenly Peace).

The project located in Beijing with area of 149,500 m2. According to the project description, this theater is composed by an opera, a concert hall and 2 theater. It is also mentioned as a city of theaters, and as you can seen on the picture above, the complex is look like a transparent island in an artificial lake.

French architect Paul Andreu is no stranger to controversy -- or to innovative forms.

A generation ago, in 1974, his untraditional design for Terminal 1 of Paris 's Charles de Gaulle airport was criticized for its unusual curves, yet Andreu's groundbreaking, futuristic building later was seen to distinguish de Gaulle from more generic European and international air hubs. (The same airport's Terminal 2E, also designed by Andreu, gained attention in 2004 when it collapsed, tragically killing four people.)

Beijing 's daring National Grand Theater is as much a spectacle as the productions that will be staged inside in the 2,416-seat opera house, the 2,017-seat concert hall, and the 1,040-seat theater. At night, the semi-transparent skin will give passersby a glimpse at the performance inside one of three auditoriums, a feature that highlights the building's public nature.
