Dear John,
What you describe resembles an azimuth sundial. See for instance the
Plochingen sundial in Karl Schwarzinger's collection:

In this case, there would be no clear-cut alignment with anything,
including the (in)famous path...

The problem is that you are halving the angle through which

So this could be called analemmatic shadow plane sundial perhaps?

Imagine a North-South meridian line on flat ground. On this line place a thin

Nice job. Original, adaptable. I suspect it can be modified to apply
to a larger scope of dials than just analemmatic. Not sure the public
would go for it aesthetically, but I admire the concept.

The problem is that you are halving the angle through which you turn the
dial. That affects the geometry of the elliptical dial. You can't just

Hi John et al,
I thought at first that John Lynes was making a joke, but you could actually
do this. If you have a large, fixed, plane mirror you can use the sunlight
reflected off it instead

Hello John L.
I’ve never heard of such a sundial and I can’t imagine how it would function.
I’m not sure I understand the setup and positioning of the mirror

Good luck, Alison!
I'll let the real experts address the weight of evidence, but you are
quite correct, and Mr. Phillips is wrong. While many types of sundials can
indeed be adjusted to operate in any location, they cannot be adjusted
to arbitrary orientation.
