This is a marvelous composition. It reminds me of the work of the
sculptor Roger Perry.
As far as I know he only did the one shown here:

However there must be many other opportunities such as covering a wall
with gnomons. As pointed out by others, if they are polar
then we can expect a solar time keeping. Otherwise it gives a forest
of shadow casters that shorten in one point. An intriguing appearance.
Experiment!
There could well be many other examples of should we call it "shadow
sculpture"?

Dear Dialists,
I am thinking about a sundial, which, to discourage vandalism, should
not have a big gnomon, but rather a number of small ones.
I thought would be neat if they could be arranged in lines, so that at
a certain hour the shadows line up, and the next 'set' lines up at
another hour.
I include a small drawing to illustrate my idea. Something in the back
of my mind keeps telling me that this might be the case for a
shadowplane sundial, but I would like the little gnomons to be
perpendicular to the face of the dial, for ease of construction.
Something is blocked in my head today, so I can't make up my mind if
it works or not ... and it has been raining all day so I can't build a
model either :-(
please give me a gentle prod in the right direction!
