There is a wooden box standing on four narrow metal legs, in the corner of the room. Walking around the piece, you may notice a small mirror placed under the box on the floor. You would naturally try to find the best position in which you can see what the mirror is reflecting. When you find the right spot you would be able to see a close up of a woman’s lips saying something. Since there is no sound coming from the box you might try to read her lips for a while. Being not quite sure if you have guessed the words correctly or not you walk away.
