Interrogation by the STASI. An interrogation of a dissident is played back in speakers set in the table. In order to hear, you put your elbows on the speaker plates and your hands over your ears. The sound propagates through your lower arm, making the palm vibrate like speaker membranes; and making you look like a broken person. It is quite ingenious.
