The big thing to do in China is a 14-minute movie filmed entirely in Circle-Vision 360[dg]. You wouldn’t believe the work it takes to make a film that surrounds you from all sides. The makers first had to figure out the optimal number of screens (nine—which enables projectors to be slipped in the gaps between screens) and then they had to suspend a ring of carefully calibrated cameras from helicopters so that the crew wasn’t in the shots. In 2002, the footage of Shanghai had to be reshot because the city no longer resembled the 1982 version that was being shown; this being China, it’s probably already time for another refresh. The result, which surveys some of the country’s most beautiful vistas, is ravishing, although the masses no longer seem to care.
