Guinness Book of Records world record holder for card stacking, Bryan Berg (not pictured), allows two people to stand on his stacked cards as a test, while he prepares to build a miniature version of the Beijing Athlete Village out of playing cards, at a promotional event in Hong Kong on July 9, 2008. Berg, a self taught artist, uses no tape or glue to create his works and plans to finish the project by July 24 - two weeks before the start of the Beijing Olympic Games.
