Makoto Hirahara designed the Bright Blind. What is it? A fake window for people who work all day long in a windowless room; it creates the illusion of sunlight.

How does it work? Uses electroluminescent sheets to present the appearance of bright light. If the light gets a bit too bright, the user just needs to adjust the blind as they would with a real one.
