A big thank you to Titus Grenyer over at Pep Organ for showing us around the Sydney Town Hall Organ, to Dr. Diana Deutsch for providing her illusions and insight into the field, to Casey Connor for advice on building sound illusions, and to Dr. Michael Bach for providing the motion-bounce illusion.
