Turn on the light, Please
Turn on the light, please. We hear this sentence every day when people consider light as functional lighting. It contributes brightness to space, but we hardly see it when it is on. A piece of glass reverses this situation. A giant ghost-like light bulb image slightly attaches to the wall surface. Scarcely does it have the afterimage, but it will deeply sink into viewers' hearts. Light no longer conquers the dark but reveals itself.
