While it is true that cards “speak” through the symbols or signs that they carry, we can also look to what cards can “do” or what can be “done with” cards, and we can see that a card is not entirely meaningless outside of a semiotic context. Cards, most basically, can be flipped. They can also be used, as Ian Hacking (1988) has shown, as agents of randomization, and simple playing cards were not only employed in the history of the search for telepathy, but cards as an “organizational system” (Hayles 2005, Chun 2005) played an important role in the history of computing, making possible serial functions and memory.
