The eye-catching building, which is nearly finished, will be the headquarters of China Central Television, the staid propaganda arm of China's ruling Communist Party, and it's perhaps the boldest and most daring of several new buildings that have given Beijing a stunning new appearance for the upcoming Summer Olympic Games.

The last of them is the new television building, the CCTV headquarters, and it can nearly make one dizzy standing on the ground and looking up at its odd, teetering 49-story towers connected by a multistory, cantilevered, jagged cross section over open space at a vertiginous 36 stories up in the air.

Designed by Dutch architect Rem Koolhaas, the building has been called an "angular marvel" and a "dazzling reinvention of the skyscraper."

Its engineering is so complex that the designers say such a building couldn't have been built a few years ago. That's because it took immense computing power.
