The 29th Olympiad Opening Ceremony showcasing the start of 2008 Summer Olympic Games was by far the most breathtaking series of mass performances I have ever seen.
China has officially outdone itself. Not only were the feats of human mass precision of power and beauty phenomenal, but the over $40 Billion in building the Olympic stadiums and surrounding skyline was well put to use because even the buildings are architectural masterpieces.
Honestly I just pity the city that has to follow that in 2012. London I think? You have a lot to live up to if you want to surpass the grandeur of China's display of artistic and technological wonder.
