Mel:
I think what you have done is really spectacular!
I have personally seen the mars/gyralight effect (I'm not quite sure which) from the cab of the CP Canadian way back in 1965. Don't ask how I was able to get a ride through Northern Ontario in the middle of the night, but I'll blame it on the other kid! Anyhow, seeing your video with the light projected onto a flat surface struck me as being pretty realistic.
Well done. Thanks for the 'How To'.

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
Personally I prefer the Gyralite/.040" spacer combination.
