Re: A tower of light
It's a beam of light which originates at the point of the pyramid which is the Luxor. I've walked completely around the Luxor, and that darned beam is ALWAYS directly overhead.
At the time I asked folks how it was done, didn't find out. That was before browsers, though, and a robust internet.
I suspect it's a laser which is radiating 360 degrees, but I don't know.
If anyone knows, I'd be interested.
