I think this is a pretty great idea, and if you work in a windowless office you might also. The Bright Blind was created by Makoto Hirahara and it basically recreates the look of a window covered by venetian blinds, but on any wall. The slats on the blinds are made from electroluminescent sheets that produce enough of a glow to recreate the look of diffused light coming from outside.
Like with real blinds, turning the plastic stick will adjust the brightness up and down but unfortunately since the original version was actually created by hand, if you want your own you better have a lot of patience and probably a lot of money.
