Let There Be Light - A New Lighting Idea

Wouldn't it be cool if you could light a room in such a way that it just "glowed?" No visible light source, just light? Here's what I'm picturing: instead of a few lamps, the whole ceiling, let's say, would glow a gentle blueish light - not so much that it was glaring, but enough to see well by. Or you could use a wall. The possibilities are endless.
Electroluminsecence (EL for short). That's the ticket. What am I talking about? EL is a technology that's been around since the early 1960's. It consists of a simple device that has a thin layer in it that glows when you apply electricity, using very little electricity in the process. It was developed by Sylvania, who called it "Panelescent." My dad worked for Sylvania, and I remember him bringing home a Panelescent nite-lite. It was a small disc, about 3 inches, that glowed blue when you plugged it in (See the picture at left). This is, by the way, the basic idea behind the Timex Indiglo watch faces. You can read more about it at http://en.wikipedia.org/wiki/Electroluminescence. Apparently, Chrysler Corp. used Panelescent lighting in their dashboards in the 1960s (read more here.)
Well, when I write these things, I usually look around to see if anyone else has already thought up my idea. Check out this website. Apparently, Light Tape Ltd. sells this stuff in rolls of tape - different colors. It looks so cool! I don't know how expensive it is, but this might be just the thing for lighting a room. What do you think? Glow on!
