Here is a video of the John Hancock Center in Chicago. Watch in HD and please subscribe! :)


The John Hancock Center at 875 North Michigan Avenue in the Streeterville area of Chicago, Illinois, is a 100-story, 1,127-foot (344 m) tall skyscraper, constructed under the supervision of Skidmore, Owings and Merrill, with chief designer Bruce Graham and structural engineer Fazlur Khan. When the building topped out on May 6, 1968, it was the tallest building in the world outside New York City. It is currently the fourth-tallest building in Chicago and the sixth-tallest in the United States, after the Willis Tower, the Empire State Building, the Bank of America Tower, the Trump Tower Chicago, and the Aon Center. When measured to the top of its antenna masts, it stands at 1,506 feet (459 m). The building is home to offices and restaurants, as well as about 700 condominiums and contains the third highest residence in the world, after the Trump Tower also in Chicago and the Burj Khalifa in Dubai. This skyscraper was named for John Hancock Mutual Life Insurance Company, a developer and original tenant of the building.
The 95th floor has long been home to a restaurant, the latest tenant being "The Signature Room on the 95th Floor." While patrons dine, they can look out at Chicago and Lake Michigan. John Hancock Center's Observatory attraction (called John Hancock Observatory) competes with the Willis Tower's Skydeck across town. John Hancock Center is in the heart of Michigan Avenue, a prime tourist hotspot in Chicago, while the Willis Tower is in the financial district. John Hancock Observatory is complete with full 360 degree views of the city, up to four states and over 80 miles. The Observatory has Chicago's only open-air SkyWalk and also features a free multimedia tour in six languages, narrated by actor David Schwimmer. From January to March, starting in 2011, the Observatory will also offer what the building management claims to be the world's highest ice skating rink, using a synthetic surface that will enable the use of standard ice skates at normal room temperature. The 44th-floor sky lobby features America's highest indoor swimming pool.

One of the most famous buildings of the structural expressionist style, the skyscraper's distinctive X-bracing exterior is actually a hint that the structure's skin is indeed part of its 'tubular system'. This idea is one of the architectural techniques the building used to climb to record heights (the tubular system is essentially the spine that helps the building stand upright during wind and earthquake loads). This X-bracing allows for both higher performance from tall structures and the ability to open up the inside floorplan (and usable floor space) if the architect desires. Original features such as the skin have made the John Hancock Center an architectural icon. It was pioneered by Bangladeshi-American structural civil engineer Fazlur Khan and chief architect Bruce Graham.
The interior was remodeled in 1995, adding to the lobby travertine and textured limestone surfaces. The elliptical-shaped plaza outside the building serves as a public oasis with seasonal plantings and a 12-foot (3.7 m) waterfall. A band of white lights at the top of the building is visible all over Chicago at night and changes colors for different events. For example, at Christmas time the colors are green and red. When a sports team goes far in the playoffs, the colors change, too. When the Chicago Bears made the Super Bowl the colors were blue and orange.
The building is a member of the World Federation of Great Towers. It also has won various awards for its distinctive style, including the Distinguished Architects Twenty-five Year Award from the American Institute of Architects in May 1999.
