 Typically, a picture from a deck such as Persona is placed on an OH word card, or the abstractions in Persona are used to draw a number of 1001 cards to develop a complex story.This makes the genre more elastic, but also potentially confusing.Using the same structural idea as The OH Cards, and with a more recent history, Shadow Cards provide an electronic demonstration on how the combination of word and picture works, but with a different process and simpler imagery (crayons rather than watercolour).
