If you watched the Opening Ceremony on Friday night, chances are you said something like, "no way that's possible" at least once. It turns out you were right.
London's Telegraph newspaper reports that some of the fireworks which appeared over Beijing during the television broadcast of the Olympic Opening Ceremony were actually computer generated. But -- hold on -- it's not necessarily as bad as you think.
The faked fireworks were actually set-off at the stadium, but because of potential dangers in filming the display live from a helicopter, viewers at home were shown a pre-recorded, computer-generated shot. It sounds dishonest, but I'm not sure it's such a terrible thing. - Yahoo! Sports
