What you'll need:
Photos from magazines, newspapers, the Internet or photos taken by yourself.
You'll need at least one photo for each person.
Create groups of 5-7 people or larger.
Mix up the photos, face down and then have each person pick one photo.
Each person has a picture but they cant show it to anyone.
The group then tries to come up with a story from some photos.
It takes a lot of patience and understanding to keep the story going in the direction that the first person started off with.
