Back in September we posted about the fake sun roof for your car, which served no practical purpose what so ever. However this pretend window is bordering on the useful, the bright blind.
Makoto Hirahara’s Bright Blind uses electroluminescent sheets (try saying that after a few beers) to simulate a window, and if the simulated sun is too bright you can turn it down by adjusting the blind. This means that even the crappiest cubicles can have the benefit of a window.
The electroluminescent does exist (prototype) but is not available to buy just yet, come on guys. More info at GNR8, found via Crib Candy with a bit more info over at the ever excellent Tree Hugger.
