Hi Roger and Mitchael,
I'm sure others have thought of and have used these concepts before us.
Sundials have been around for a long time.
What these concepts achieves are:
That all clocks have a energy source to make them work. For sundials it is the
rotation of Earth. And that planet Earth

Sure, any type of dial is fine if it works for the situation.

Alright, acknowledged. But, even so, why not instead have a class design
and build a dial whose construction-derivation would be of interest to
them. ...or even build, or have it built, for them.
...such as any central-gnomon Equatorial, or any Flat Dial that's

An analemmatic dial is more considered more interesting than other kinds
because it is somewhat interactive, but I agree that it is a little
harder to understand. To me though, installing a sundial at a school
isn't just about, or even primarily about, the teaching of the mechanics
of how it

I've just realized that I mis-spelled "aperture". I don' t know why I added

As Hunt pointed out, there might be many locations where an Anelematic is
the only dial that won't be stolen or vandalized. And I like it. But I'd
consider it a last-resort, to be used only when a previous dial has been
stolen or vandalized. That's because I prefer sundials whose

In general, there are some people who are able to make a little money
making sundials but most would not claim to make a 'living' or anything
like that.
