Some poker pros, like World Series of Poker champ Carlos Mortensen, are well-known for their elaborate ways of stacking their chips. Some others make crazy castles out of their ammunition at the poker table. However none can compare to a miniature city made of chips.

That’s what artist and sculpture professor Liu Jianhua painstakingly constructed a handful of years ago using an incredible array of styles and colors.

If unbelievable chip stacks weren’t enough, there are some people out there who love making complex structures out of playing cards. Bryan Berg, a Harvard-educated architect and Guinness world-record holder, a few years ago made a replica of Venetian Macau out of 218,792 cards. He apparently makes a living just from stacking cards.
