Theodore Watson’s Audio Space allows you to leave messages in specific locations within the room. Wearing a headset equipped with earphones and a microphone, visitors record messages that are then placed in the spot where it was recorded.
Through the earphones, the messages are played along with those recorded by previous visitors. Each message sounds as if it is coming from the spot where it was recorded. The resulting effect is the sensation of walking through a space inhabited by ghosts, with each visitor leaving an aural mark for others to uncover.
