It has a monitor and a mirror that reflects light from the monitor. Are the light emitted by the monitor and the light reflected by the mirror different?
The world of the monitor and the world of the mirror merge with light as a medium. If the mirror only reflected the light from the monitor, it is no longer possible to tell if the light originated from the monitor or the mirror. The boundaries between the world of mirrors and monitors have collapsed and merged. And it leads us to another world.
