Hi Jack: I don't have time to look for it right now, and my bad memory won't let me recall where I saw it, but earlier this year we discussed a german invention of an indoor sundial just like what you describe- with a mechanical driven moveable light mounted in the ceiling that cast a shadow fron a wall-mounted gnomon onto a wall sundial inside a building. Try searching for "indoor sundials" or "mechanical sundials". If you can find that email thread, there are photos of it.

What we need is for somebody to develop a motor-driven, geared apparatus that will move an electric through a path that picks up all the relevant celestial motions.
