This is my personal experience of using Augusto Boal’s methods while at University. We performed a piece which incorporated a few of Augusto Boal's methods. In part it was invisible theatre because the 'audience/spectactor' was not privvy to what was going on, but able to interact, but also in part it utilised his Image Theatre techniques. What happened was.... 'interesting'- not a day either I, nor anyone involved in it would forget in a hurry. Interview with Boal: www.youtube.com Ad Astra Per Aspera .
