This improv game is in the following improv game categories:
All players in a circle, or a long line. One player starts a little gesture, with or without a little sound..
The next player takes it over and makes it bigger. The last player does the
whole thing to the extreme.
Make sure the players stick to the original gesture/sound, and don`t just do
their own thing. We should be able to see the movement grow organically.
