As a bridge between opening circle and breakout sessions, group exercises are an excellent way to reinforce the ethics of contributing your voice and speaking with friends you have not yet met. The following are suggested group exercises.
Spectrogram is an excellent exercise for letting participants "show where they stand" and allowing them to discover allies and new perspectives on relevant issues.
Strong Wind Blows is a fun game to get the blood flowing in the morning, while also allowing the group to discover common bonds in an often humorous way.
SpeedGeeking is a wild and wacky way to automate and expedite the time honored "brain dump", allowing participants to brief each other on their projects and work in a fast and furious format.
