From the Institute for Experiential Education:

"Chiji Processing Cards are a standard in the experiential education field. Not simply pretty pictures on a deck of playing cards, they are a valuable educational tool for all experiential educators who recognize processing (or debriefing) as the most challenging part of quality facilitation. Spread out among a group of people, the cards are forty-eight images that assist participants in creating their own metaphors. Thousands of decks have been sold to counselors, ropes course facilitators, classroom teachers, therapeutic recreation specialists, adventure programmers, camp counselors, and corporate trainers."
