Zener cards were developed in the 1930s by Karl Zener for J. B. Rhine's forced-choice ESP experiments at Duke University. Five symbols: circle, plus, waves, square, star.
This instrument runs the protocol under commitment-before-call. The deck is generated and sealed server-side before your first call, and revealed only after all twenty-five calls are committed. You call blind; the instrument holds the deck. During the run there is no feedback.
