As we exit the auditorium, Robin won't disclose the budget for fear he says of distracting from the performances. The play includes archive video projections and revolving sets.
The floor's supported by ten massive pads. These are constructed from rubber, and so are able to absorb any vibrations from outside and prevent them from affecting the auditorium.
If you are in a room like this auditorium, you might have a little bit of amplification, but of course the public address system does most of the work for you.
