in 1982. I think
Edley McKnight's idea would be a good possibility even over two stories
and with some
angle changes.

Of course there are any number of ways that the information could be
sampled and sent in a discrete fashion. A set of tubes or slits at the
top with different colored filters at their inner end could reflect a color
down the pipe to indicate the time for instance.
A slotted gnomon over a transparent horizontal sundial with different
colored sectors
would work quite nicely. This would be much easier than 11 to 13
separate sections or tubes
for each hour. Certainly an optical dial (panorama or fish eye view of
the sky) would be
interesting but much more complicated and expensive with the number of
field lens needed
down such a long tube.
