回顾了迈克尔杰克逊的1993 Superbowl 中场表演，看到全场用彩色卡片组成图案，想起来近几年老看到朝鲜组织表演玩儿这个，突然想知道是谁最早使用过。网上一搜就，还真有：
A milestone in collegiate sports pageantry was reached in 2008 – the 100th anniversary of the first card stunt performed at the Cal-Stanford game in 1908. Throughout the years, over 1 million people have participated in flipping cards at football games. In the heyday of the 1950s, almost 30 colleges had card stunts performed during football games. Today, there are only 5 schools that carry on this colorful tradition. Card stunts are also now performed at many different sporting events. 6park.com
最早看来是1908年美国Cal 对斯坦福的比赛上的。之后50年代30多所大学都在橄榄球比赛上有卡片组图表演。现在只有5所学校还保留这个。原来朝鲜老拿出来耍的东西是美国50年代大学玩儿剩下的。独裁制度的创造力真是贫乏。
