saw this at a youth retreat in neighboring parish, not exactly an ice breaker, but idea was intriguing and put kids off balance, so they did not know what to expect, and hence seemed more open-minded.
the day was broken up as was the space, meal, snack and some art type activities were in one room, and the actual talks or presentations (brief, 20 minutes or less) were in a larger space.
for each of the talks or sessions which took place in the larger space, the organizer re-arranged the seating.
once chairs were in rows,
once in a large circle
once in small circles
once there were carpet squares on the floor
and once a mix of chairs and floor.
each participant had a color coded nametag, and there were colored posties on each seat, which were moved around each time, so nobody got the same seat, nobody sat together with a buddy, and the group was forced to move out of cliques.
the reason for the seating arrangment was explained in the talk, and they were keyed to the theme of the talks. and each talk gave directions for the next “hands-on” actvity, which was done with the people in the new seating groups working together.
the overall theme was service and discipleship, title was "Show up for Your own Life."
can’t remember all the activities but one was making a headband with a symbol related to how you see yourself as a member of the Body of Christ. Another was a pennant for your car antenna with an evangelization slogan. a third was writing a rap, TV commercial or other advertising jingle for the theme “Show up”.
