After seeing Smilodon's post on his apartment door, I had to give it a try myself. I happen to have a double closet door in my theater that would be perfect for replacing, and so I got to work. Being a Lord of the Rings fan since I was a boy, the doors to the Mines of Moria were the perfect subject. After many hours and a few restarts, here is the result: and with the lights on: Rather than do a full writeup here, if you are interested in reading more (and you should be, since they come on automatically when it is dark, and open automatically when the right word is spoken in elven ), I put up a page with probably more info than anyone would want to see. Thanks Smilodon and others for posting their knowledge of edge-lighting etched plexiglass!
