We had to do one in training that made no sense to me, but here it is. Our instructor pulled 4 of us up to the front of the class and put all of us back to back. So imagine us facing like this + , she then said now walk to me. So we all stood back to back and moved to her location while telling the ones who were looking in the opposite directions when to move and what direction. That part made sense, I guess, but it went a little weird when the point of it was what happens when you have bad teachers. She told us to do it again, but said "I never told you to stay back to back." So we were confused and walked to her casually and she said, see how easy that was, thanks now have a seat. She said "commuincation is key, and it's easy to be confused with bad instructions, which is why they stayed back to back."
I guess it makes more sense typing it out, but the teamwork thing would of made more sense in the end. Also since I am now interested in this topic, I found this and hopefully it helps. http://www.onlineexpert.com/elearning/user/pdf/natsem/managingdiverseworkforce/team-buildinggamesactivitiesideas.pdf
