Mastering the Crowd: The Technique of Stadium Card Stunts

College bowl season is upon us and with it comes not just the football games, but also the intricate “card stunts” performed by stadium audiences. These highly-coordinated crowd work is capable of producing detailed images similar to pixelated images on computer screens. Michael Littman’s new book, “Code to Joy: Why Everyone Should Learn a Little Programming,” provides an accessible and entertaining guide to the basics of programming for fledgling coders of all ages and details how we need not distrust an automaton-filled future so long as we learn to speak their language. Card stunts have come a long way since their start in college sports in the 1920s. They leverage the fact that the members of a stadium crowd sit in seats arranged in a grid and transform themselves into something like a big computer display screen.
