I love it! If Tom can sell his neighbor on the esthetic upgrade to his house, it's a great solution. How does the geometry work out? Would the mirror need to be *very* high, say, over 2 stories itself? Closer, or farther than Tom's South wall? I guess the design trick would be to calculate a

I sketched out a vertical dial, figuring a mirror as the nodus on a pin gnomon perpendicular to the dial face, using Fer J. de Vries' ZW2000 software. I used my northern California coordinates. It's a *little* large, for a suburban home. A mirror 10 feet from the plane of the wall seems to

Dear all, I am going to Granada, Cordoba and Seville in Andalusia, Spain very shortly and wondered whether somebody might be able to point out a few dials or astrolabes in the area. Thanks: Heiner 51N/1W -

Hi Tom: Is a skylight hole in your roof possible? This would eliminate most of your problems with mirrors. You don't need a flat roof. A skylight hole could be used for any of the interior dials I mentioned. John L. Carmichael Jr.925 E. Foothills Dr.Tucson Arizona, USATel:

There is an other solution: Put a miiror high on your south facing wall which will reflect the sun on your neighboors North wall. Design a sundial for that North Facing wall of your neighboor. He will never look at it but you see it all the time. Thibaud At 07:36 04-01-2004, you wrote: I

It is not that difficult, mirror the neighbors wall in relation to the mirror, so it will be some imaginary wall in Tom's house. The mirror is the tip of the gnomon, or a little window whatever you like. The south facing dial on the mirrored neighbors wall has to be mirrored back: left and
