A desk lamp reports its most recent experience.
Instead of a light-emitting lampshade there is a sound-emitting loudspeaker. When using the switch, a sound similar to the sound caused by writing can be heard.
In the nearby study there is a lamp on the desk. When switching it on, the lighting conditions stay the same. Instead of it one can hear the scratching of a nib. - The lampshade is a loudspeaker!
