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 require
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 ri

I love it!
If Tom can sell his neighbor on the esthetic upgrade to his house, it's a

say, over 2 stories itself? Closer, or farther than Tom's South wall? I
guess the design trick would be to calculate a Sou
Hi Tom:
Is a skylight hole in your roof possible?

flat roof. A skylight hole could be used for any of the interior dials I
mentioned.

>I think I can now properly formulate my question: Is there a way to get
the sun's rays down to my room so I can have them illuminate an ordinary
sundial? (Without demolishing my neighbor's house or spending a ton of
money?)<
Not perhaps
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.
