This is a version of the activity Ego-AlterEgo Karl Rohnke wrote up in Funn 'n Games (or FUNN Stuff before that). With the help of Scott Moulton, we have an Ubuntu twist on the activity. We like how the Ubuntu Card deflects the emotion from the people to the imagery on the cards and adds a layer to the discussion.
Have every group member stand in a circle while holding an Ubuntu Card single image facing out toward the group. Ask each person to secretly choose a Ubuntu Card image to represent their "Protector" and then to secretly choose an image to represent their "Destroyer". On Go, each player must attempt to keep the person holding their protector image between themselves and their destroyer image. I might recommend a fast walking place. This tends to be a fun, quick and confusing exercise. Take time to talk about strategies, success and struggles participants encountered. Ask why they picked certain images to represent those roles.
You can play several rounds changing the rules slightly each round to bring up different discussion points.
Try changing the name of the "Destroyer" image to the "Bully" image. How does that effect the game? Did that feel different? How does a victim feel when they see their bully in school?
Try changing roles. Instead of choosing a "Protector" and a "Bully", have each person play the role of the "Protector". Have them secretly choose an image to represent a "Victim of Bullying" and other to represent the "Bully". This version tends to look a bit like a mosh pit with all participants rushing into the middle to protect...be aware of what your group can handle. After this version, you can ask about strategies and differences. You can ask about who they have as protectors or who they protect in life.
