Card stunts are a planned, coordinated sequence of actions performed by an audience, whose members raise cards that, in the aggregate, create a recognizable image. The images they create can range widely and, through careful planning, the same cards can create a number of different images by systematically changing how the cards are held up. Although card stunts are now performed at a variety of events ranging from sports to political rallies, the card stunt is closely associated with American football, particularly college football, as well as football (soccer) where it can form part of a tifo. The North Korean mass games Arirang Festival, however, were the first to extend the card stunt to an art form, using flip-book cards to produce enormous hour-long animated sequences.
In Mexico's Heroic Military Academy, card stunts are done during various occasions, especially on September 13, the anniversary of the Battle of Chapultepec, where a program is made in honor of this great battle.
North Korea's yearly Arirang Festival, also known as the Mass Games, in Pyongyang capitalizes on choreography and card stunt to create sweeping images across the stadium. The festival is famed for the use of this technique as part of the iconographic propaganda art of the regime.
Card stunts (Thai: การแปรอักษร) are regularly performed in certain sporting events in Thailand. They are especially associated with Jaturamitr Samakkee and Chula–Thammasat Traditional Football Match, but are also employed in most school- and university-level sporting events where performances by the seated crowd often play an important part in the competition. In addition to plain colored cards, other objects such as umbrellas, flashlights and reflective surfaces are also used, and special plates with multiple tiles of colored card booklets are used to create detailed aggregate images.
