If you could go back in time, say twenty years ago, what would you say to yourself? How about two seconds ago?
When the audience talks into the phone, the wireless microphone captures the voice, delays it 2 seconds, and plays it back along with the audio from the twenty-year-old VHS video that’s playing in the background. The audience experiences three voices at the same time: voices from 20 years ago, 2 seconds ago, and the present.
