The opening ceremony of the Beijing Olympic Games on August 8 stunned the world, with its fascinating and glamorous art performance and visual effects. Many who witnessed the spectacular said it was like an epic movie, and of course, like many of today's blockbusters, it owed much to the use of cutting-edge technology.

The ceremony, featuring huge LED (light-emitting diode) screens, eye-catching lighting systems and inspiring multimedia video shows, involved dozens of advanced technologies, including materials for spaceships, according to Yu Jianping, head of the technology group for the opening ceremony, who led a 500-strong team of experts.

"The technology used at the Games' opening ceremony was some of the most complicated in history," Yu said, describing the gala as a perfect combination of advanced technology and great originality.

For example, at the top of the National Stadium where the opening ceremony was held is a 147-meter-long, 22-meter-wide LED screen, one of the biggest in the world. There was also a 36-meter-long, 30-meter-wide structure, with a total of 11 separate elevated platforms.

From the elevated platform to the video system, the creation team had worked hard to ensure that the whole ceremony went without a hitch.

"Since all of the facilities were completed on June 10, we had only two months to tackle any problems," said Yu, who is also the deputy designer of Shenzhou 7, China's third manned spacecraft that is expected to enter orbit in October.

"We are living in a hi-tech time and I think to present China's ancient culture through high technology is a more effective way to attract the young generation," said Zhang Yimou, Chief Director of the opening ceremony and a renowned Chinese filmmaker.

On Yu's initiative, state-of-the-art technology was introduced into many aspects of the ceremony. Apart from the huge LED screen and elevated platform, the globe that rose up at the end of the art performance was another highlight.

With a diameter of 18 meters, the globe weighs around 16 tons and can be raised to a height of 24 meters. A total of 58 stunt men performed on the globe, with half of them upside down part of the time.

"It was the first time such a huge globe was used in China," Yu said. "The material on its surface was a kind of flexible aluminum."

Their other creations included a huge scroll, 20 mm thick and weighing around 0.8 kg, and a digital direction and control system.

"Apart from the communications system, all of the technology we used was developed by local companies," Yu said.
